42512-63-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42512-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,1 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42512-63:
(7*4)+(6*2)+(5*5)+(4*1)+(3*2)+(2*6)+(1*3)=90
90 % 10 = 0
So 42512-63-0 is a valid CAS Registry Number.

Synthesis of five- and six-membered dihalogenated heterocyclic compounds by electrophile-triggered cyclization

Ji, Ke-Gong,Zhu, Hai-Tao,Yang, Fang,Shaukat, Ali,Xia, Xiao-Feng,Yang, Yan-Fang,Liu, Xue-Yuan,Liang, Yong-Min

supporting information; experimental part, p. 5670 - 5678 (2010/11/05)

Highly substituted dihalogenated dihydrofurans, dihydropyrroles, and dihydro-2H-pyrans bearing alkyl, vinyl, aryl, and heteroaryl moieties can be prepared in good to excellent yields (up to 99%) by allowing 1,4-butyne-diol, 4-aminobut-2-yn-1-ol, and pent-2-yne-1,5-diol derivatives to react with different electrophiles (I2, IBr, and ICl) at room temperature. Both halogen atoms generated from electrophiles were used effectively. The resulting halides can be further exploited by using palladium-catalyzed coupling reactions. The presence of trace amount of water is essential for this electrophilic cyclization.

Iterative synthesis of oligo-1,4-diols via catalytic anti-Markovnikov hydration of terminal alkynes

Kribber, Thomas,Labonne, Aurelie,Hintermann, Lukas

, p. 2809 - 2818 (2008/03/14)

A sequential, iterative synthesis of oligo-1,4-diol building blocks has been realized via (a) propargylation of an aldehyde with allenylzinc bromide, (b) alcohol protection and (c) ruthenium-catalyzed anti-Markovnikov hydration of the terminal alkyne to r
