Check Digit Verification of cas no

The CAS Registry Mumber 5755-71-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5755-71:
(6*5)+(5*7)+(4*5)+(3*5)+(2*7)+(1*1)=115
115 % 10 = 5
So 5755-71-5 is a valid CAS Registry Number.

supporting information, p. 9454 - 9459 (2021/12/09)

Presented is a light-promoted C-C bond forming reaction yielding sulfone and phosphate derivatives at room temperature in the absence of metals or photoredox catalyst. This transformation proceeds in neat conditions through an auto-oxidation mechanism which is maintained through the leaching of trace amounts of O2 as sole green oxidant. This journal is
