Check Digit Verification of cas no

The CAS Registry Mumber 21151-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21151-49:
(7*2)+(6*1)+(5*1)+(4*5)+(3*1)+(2*4)+(1*9)=65
65 % 10 = 5
So 21151-49-5 is a valid CAS Registry Number.

Nucleo-Palladation-Triggering Alkene Functionalization: A Route to γ-Lactones

Zheng, Meifang,Chen, Pengquan,Huang, Liangbin,Wu, Wanqing,Jiang, Huanfeng

, p. 5756 - 5759 (2017/11/10)

An unprecedented strategy for the highly effective synthesis of γ-lactones from homoallylic alcohols was achieved by palladium catalysis in one step. The protocol affords aryl, alkyl, and spiro γ-lactones directly from readily available homoallylic alcohols in good yields with excellent functional group tolerance and high chemoselectivity under mild conditions.
