Check Digit Verification of cas no

The CAS Registry Mumber 53512-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,1 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 53512-53:
(7*5)+(6*3)+(5*5)+(4*1)+(3*2)+(2*5)+(1*3)=101
101 % 10 = 1
So 53512-53-1 is a valid CAS Registry Number.

Antenna-initiated photochemistry in polyfunctional steroids. photoepimerization of 3α-(dimethylphenylsiloxy)-5α-androstane-6,17-dione and its 3β isomer by through-bond exchange energy transfer

Wu, Zheng-Zhi,Nash, John,Morrison, Harry

, p. 6640 - 6648 (2007/10/02)

We have previously reported that photolysis of 3α-(dimethylphenylsiloxy-5α-androstane-11,17-dione, in the presence of triethylamine (TEA) and with 266-nm light so as to selectively excite the dimethylphenylsiloxy (DPS) "antenna", primarily gives rise to t
