Check Digit Verification of cas no

The CAS Registry Mumber 123-81-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123-81:
(5*1)+(4*2)+(3*3)+(2*8)+(1*1)=39
39 % 10 = 9
So 123-81-9 is a valid CAS Registry Number.

A liquid organic tin antimony compound and its preparation method and application (by machine translation)

-

Paragraph 0030; 0031, (2017/01/26)

The invention relates to a liquid organic tin antimony compound and its preparation method, compounds of tin and antimony in the total content is more than 18%, its preparation method is as follows: (1) will be mercapto acetic acid, catalyst and dihydric alcohol mixing, stirring, heating to 70 - 120 °C, vacuum degree is - 0.06 - - 0.09 mpa conducted under the conditions of the reaction, the reaction to the water separator was no longer in the water to trickle out, cooling to room temperature, water washing, takes the oil phase, distillation and dehydration under reduced pressure, to obtain the mercapto compound; (2) step (1) made of a mercapto compound, isooctyl thioglycolate, methyl chloride and water mixing, heating up to 40 - 80 °C, into the antimony trioxide, adding inorganic alkali to adjust the pH value is 6 - 8, then the stirring reaction 4 - 6 hours, after the reaction takes the oil phase, dewatering filtering, to obtain the liquid organic tin antimony compound. The invention organic tin antimony compound metal content is high, low toxicity and environmental protection, is suitable for various types of hard PVC material, has an excellent initial and long-term thermal stability, product high transparency.

Synthesis of 12- and 13-membered sulfur-containing lactones by homolytic macrocyclization of mercaptoacetic esters with alkynes

Demchuk,Lazareva,Lindeman,Khrustalyov,Struchkov,Ismagilov,Troyansky,Nikishin

, p. 307 - 311 (2007/10/02)

Starting from mercaptoacetic acid esters of 1,2- or 1,3-diols and substituted acetylenes 12- and 13-membered sulfur-containing lactones as 1:1 adducts were synthesised in yields up to 48%. The mechanism of this homolytic reaction, which is initiated by the tripropylborane/oxygen system, includes generation of thiyl radicals and their addition to the triple bond of alkynes.
