Check Digit Verification of cas no

The CAS Registry Mumber 156539-36-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,3 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156539-36:
(8*1)+(7*5)+(6*6)+(5*5)+(4*3)+(3*9)+(2*3)+(1*6)=155
155 % 10 = 5
So 156539-36-5 is a valid CAS Registry Number.

A Facile Method to Append Peptidal Side-Chains onto Steroidal Templates

Horwell, David C.,Lennon, Ian C.,Roberts, Edward

, p. 4225 - 4234 (1994)

Side-Chains corresponding to phenylalanine, tyrosine and tryptophan are introduced onto a steroid template in a highly efficient manner via a condensation of the appropriate lithium acetylide with a steroidal ketone.The subsequent acetylene functionality can be selectively reduced in the presence of a modified benzyl ether and steroid ring unsaturation.
