Check Digit Verification of cas no

The CAS Registry Mumber 139618-41-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139618-41:
(8*1)+(7*3)+(6*9)+(5*6)+(4*1)+(3*8)+(2*4)+(1*1)=150
150 % 10 = 0
So 139618-41-0 is a valid CAS Registry Number.

ENANTIOCONTROLLED SYNTHESES OF THE CUPARENE SESQUITERPENES, (-)-HERBERTENE, (+)-β-CUPARENONE, (-)-DEBROMOAPLYSIN, AND (-)-APLYSIN

Takano, Seiichi,Moriya, Minoru,Ogasawara, Kunio

, p. 329 - 332 (2007/10/02)

Enantiocontrolled syntheses of the Cuparene sesquiterpenes, (-)-herbertene, (+)-cuparenone, (-)-debromoaplysin, and (-)-aplysin, have been achieved starting from the optically active tricyclic dienone by employing a Fischer indolization reaction under non-acidic conditions as the key step.
