Check Digit Verification of cas no

The CAS Registry Mumber 1425928-63-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,5,9,2 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1425928-63:
(9*1)+(8*4)+(7*2)+(6*5)+(5*9)+(4*2)+(3*8)+(2*6)+(1*3)=177
177 % 10 = 7
So 1425928-63-7 is a valid CAS Registry Number.

Synthesis of [1,4]Thiazino[4,3- a]indol-10-one Derivatives through Radical Anti Aza-Michael Addition of 2′-Aminochalcones

Zhang, Pingshun,Yang, Linjie,Chen, Wanzhi,Liu, Miaochang,Wu, Huayue

supporting information, p. 6094 - 6098 (2021/08/01)

An efficient method for the synthesis of [1,4]thiazino[4,3-a]indole derivatives using sodium chlorodifluoroacetate (ClCF2CO2Na) and elemental sulfur as the difluoromethylthiolating reagent system has been developed. Three-component reactions of 2′-aminochalcones, sulfur, and ClCF2CO2Na under basic conditions using TEMPO as the oxidant afforded [1,4]thiazino[4,3-a]indol-10-ones containing a difluoromethyl thioether moiety in good yields. Four bonds including one C-N, two C-S, and one C-C bonds are selectively formed in the sequential transformation process.
