Check Digit Verification of cas no

The CAS Registry Mumber 17271-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,7 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17271-70:
(7*1)+(6*7)+(5*2)+(4*7)+(3*1)+(2*7)+(1*0)=104
104 % 10 = 4
So 17271-70-4 is a valid CAS Registry Number.

Enantioselective Resolution Copolymerization of Racemic 2,3-Disubstituted cis-Epoxides with CO2 Mediated by Binuclear Cobalt(III) Catalyst?

He, Guang-Hui,Liu, Yan-Lan,Liu, Ye,Lu, Xiao-Bing

, p. 2386 - 2390 (2021/07/12)

Enantioselective resolution copolymerization of racemic internal epoxides with carbon dioxide (CO2) is a challenging issue because of their poor reactivity and complicated regio/stereoselectivity. Herein, we describe the first enantioselective
