Check Digit Verification of cas no

The CAS Registry Mumber 1160839-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,8,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1160839-21:
(9*1)+(8*1)+(7*6)+(6*0)+(5*8)+(4*3)+(3*9)+(2*2)+(1*1)=143
143 % 10 = 3
So 1160839-21-3 is a valid CAS Registry Number.

Forging C?S(Se) Bonds by Nickel-catalyzed Decarbonylation of Carboxylic Acid and Cleavage of Aryl Dichalcogenides

Zhou, Jing-Ya,Zhu, Yong-Ming

, p. 2452 - 2461 (2021)

A nickel-catalyzed decarbonylation of carboxylic acids cross-coupling protocol has been developed for the straightforward C?S(Se) bond formation. This reaction is promoted by a commercially-available, user-friendly, inexpensive, air and moisture-stable nickel precatalyst. Various carboxylic acids and a wide range of aryl dichalcogenide substrates were tolerated in this process which afforded products in good to excellent yields. In addition, the present reaction can be conducted on gram scale in good yield.
