Check Digit Verification of cas no

The CAS Registry Mumber 88739-11-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,7,3 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88739-11:
(7*8)+(6*8)+(5*7)+(4*3)+(3*9)+(2*1)+(1*1)=181
181 % 10 = 1
So 88739-11-1 is a valid CAS Registry Number.

Total Syntheses of Crinipellins Enabled by Cobalt-Mediated and Palladium-Catalyzed Intramolecular Pauson–Khand Reactions

Huang, Zhihui,Huang, Jun,Qu, Yongzheng,Zhang, Weibin,Gong, Jianxian,Yang, Zhen

, p. 8744 - 8748 (2018)

Efficient total syntheses of the naturally occurring, potent antibiotic compounds (?)-crinipellin A and (?)-crinipellin B are described. The key advanced intermediate, a fully functionalized tetraquinane core, was constructed by a novel thiourea/palladium-catalyzed Pauson–Khand reaction. This intermediate can serve as a common intermediate for the collective total synthesis of other members of the crinipellin family.
