Check Digit Verification of cas no

The CAS Registry Mumber 1135993-41-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,5,9,9 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1135993-41:
(9*1)+(8*1)+(7*3)+(6*5)+(5*9)+(4*9)+(3*3)+(2*4)+(1*1)=167
167 % 10 = 7
So 1135993-41-7 is a valid CAS Registry Number.

Synthesis of the neuroactive steroid antagonist 17-phenyl-5α-androst- 16-en-3α-ol by a palladium-catalysed coupling reaction

Bian, Xiaoqin,Li, Shuangshuang,Gang, Xin,Liu, Lanhai,Xie, Zengyang,Wang, Cunde

experimental part, p. 422 - 424 (2009/06/02)

The neurosteroid antagonist, 3α,5α-17-phenylandrost-16-en-3-ol, which selectively antagonises the GABA- modulatory and GABA-mimetic effects of 3α,5α-tetrahydroprogesterone and related 5α-pregnanes, was synthesised by a new route using palladium-catalysed coupling reaction as a key step. Commercially available 3α-hydroxy-5α- androstan-17-one gave the desired product in 4 steps with an overall yield of 79.5%.
