Check Digit Verification of cas no

The CAS Registry Mumber 19939-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,3 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19939-78:
(7*1)+(6*9)+(5*9)+(4*3)+(3*9)+(2*7)+(1*8)=167
167 % 10 = 7
So 19939-78-7 is a valid CAS Registry Number.

Yuan, Jin-Lan,Lu, Zhi-Zhen,Chen, Gui-Xian,Ding, Wei-Pei,Zhou, Bing-Nan,et al.

, p. 1058 - 1060 (2007/10/02)

A new pregnane glycoside, mardekoiside A was isolated from the stems of Marsdenia koi (Asclepiadaceae) and its structure was elucidated from chemical and spectral data as 12-cinnamoyl-dihydrosarcostin-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1->4)-O-β-D-oleandropyranosyl-(1->4)-O-β-D-cymaropyranoside. Key words: Marsdenia koi; Asclepiadaceae; preganane glycoside; marsdekoiside A; structure elucidation.
