Check Digit Verification of cas no

The CAS Registry Mumber 20893-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,9 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20893-19:
(7*2)+(6*0)+(5*8)+(4*9)+(3*3)+(2*1)+(1*9)=110
110 % 10 = 0
So 20893-19-0 is a valid CAS Registry Number.

, p. 2555 - 2566 (2018)

A facile chlorolactonization of alkenoic acids by treatment with diphenyl sulfoxide/oxalyl chloride has been developed. The reaction can generate various chlorolactones in moderate to good yields, wherein the chlorodiphenylsufonium salt derived from diphenyl sulfoxide/oxalyl chloride serves as the source of Cl +.
