Check Digit Verification of cas no

The CAS Registry Mumber 19825-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19825-41:
(7*1)+(6*9)+(5*8)+(4*2)+(3*5)+(2*4)+(1*1)=133
133 % 10 = 3
So 19825-41-3 is a valid CAS Registry Number.

BIFLAVANOIDS, NORDITERPENES AND A NORTRITERPNE FROM PODOCARPUS URBANII

Dasgupta, Binayak,Burke, Basil A.,Stuart, Kenneth L.

, p. 153 - 156 (1981)

Key Word Index - Podocarpus urbanii; Podocarpaceae; biflavanoid; urbalactone, a new norditerpene: 2,3-dihydropodolide; podolide; nagilactone C; norditerpene, C27H44O6. The structures of a biflavanoid, two new norditerpenes, urbanolactone and 2,3-dihydropodolide, an ecdysterol, as well as a known biflavanoid, nagilactone C and podolide from Podocarpus urbanii were elucidated.
