Check Digit Verification of cas no

The CAS Registry Mumber 89326-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,2 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89326-58:
(7*8)+(6*9)+(5*3)+(4*2)+(3*6)+(2*5)+(1*8)=169
169 % 10 = 9
So 89326-58-9 is a valid CAS Registry Number.

LONG-ACTING CONTRACEPTIVE AGENTS: NORETHISTERONE ESTERS OF ARYLCARBOXYLIC ACIDS

Wan, A. S. C.,Ngiam, T. L.,Leung, S. L.,Go, M. L.,Heng, P. W. S.,et al.

, p. 309 - 320 (2007/10/02)

The synthesis of esters of norethisterone (17α-ethynyl-17β-hydroxyestr-4-en-3-one) with acids containing a benzene ring is described, two methods of esterification being compared in terms of yield and convenience.The activities of these esters as long-acting contraceptive agents have been evaluated.
