2634-49-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2634-49-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,3 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2634-49:
(6*2)+(5*6)+(4*3)+(3*4)+(2*4)+(1*9)=83
83 % 10 = 3
So 2634-49-3 is a valid CAS Registry Number.

Montmorillonite clay catalysis. Part 15 backbone rearrangement of 4,4- dialkylcholest-5-enes catalyzed by montmorillonite K-10

Duan, Hui-Yun,Wang, Jian-Xin,Li, Tong-Shuang

, p. 3197 - 3205 (2007/10/03)

In the presence of montmorillonite K-10 4,4-dialkylcholest-5-enes undergo backbone rearrangement to give (20R)- and (20S)-4,4-dialkyl-5β,14β- dimethyl- 18,19-dinor-8α,9β,10α-cholest-13(17)-enes in high yields.
