Check Digit Verification of cas no

The CAS Registry Mumber 136880-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,8 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136880-76:
(8*1)+(7*3)+(6*6)+(5*8)+(4*8)+(3*0)+(2*7)+(1*6)=157
157 % 10 = 7
So 136880-76-7 is a valid CAS Registry Number.

Structure elucidation of restriction, a novel antifungal agent from Penicillium restrictum

Hensens,Wichmann,Liesch,VanMiddlesworth,Wilson,Schwartz

, p. 3915 - 3924 (1991)

The structures and absolute stereochemistry of restriction (1), its N,N-dimethyl derivative (4) and desglycyl hydrolysis product (3), isolated from Penicillium restrictum, have been determined on the basis of spectroscopic evidence. They belong to a new class of broad spectrum antifungal agents representing substituted tetrahydropyranyl ethers incorporating triene and glycyl ester side chains.
