Check Digit Verification of cas no
The CAS Registry Mumber 26293-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,2,9 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 26293-93:
(7*2)+(6*6)+(5*2)+(4*9)+(3*3)+(2*9)+(1*3)=126
126 % 10 = 6
So 26293-93-6 is a valid CAS Registry Number.

Paragraph 0013-0016, (2019/11/12)
The invention discloses a 2, 4 - dichloro - 6 - cyano pyrimidine synthesis method, 1st step, there will be no [...] and phosphorus oxychloride according to weight ratio of 1:5 - 8 mixed, heated to reflow the reaction 5 - 7 hours, evaporating the excess of phosphorus oxychloride is pressurized, then rectification to get intermediate B; 2nd step, the intermediate B dissolved in non-water in tetrahydrofuran, adds by drops uncle butylamine after the reaction is finished, purified get intermediate C; 3rd step, the intermediate C and thionyl chloride according to weight ratio of 1:3 - 5 mixed, heating reflux reaction 4 - 6 hours, cooling, evaporating the excess thionyl chloride, ice water quenching, purification, drying, concentration followed by recrystallization of the product. The invention improves the yield, the time is shortened, the operation is simple, simplifying the post-treatment process, increasing the safety of operation. (by machine translation)
