Check Digit Verification of cas no

The CAS Registry Mumber 87745-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,4 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87745-66:
(7*8)+(6*7)+(5*7)+(4*4)+(3*5)+(2*6)+(1*6)=182
182 % 10 = 2
So 87745-66-2 is a valid CAS Registry Number.

Rhodium-Catalyzed Regioselective Hydroformylation of Alkynes to α,β-Unsaturated Aldehydes Using Formic Acid

Fan, Chao,Hou, Jing,Chen, Yu-Jia,Ding, Kui-Ling,Zhou, Qi-Lin

, p. 2074 - 2077 (2021)

A rhodium-catalyzed hydroformylation of alkynes with formic acid was developed. The method provides α,β-unsaturated aldehydes in high yield and E-selectivity without the need to handle toxic CO gas.
