Check Digit Verification of cas no

The CAS Registry Mumber 1938062-31-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,3,8,0,6 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1938062-31:
(9*1)+(8*9)+(7*3)+(6*8)+(5*0)+(4*6)+(3*2)+(2*3)+(1*1)=187
187 % 10 = 7
So 1938062-31-7 is a valid CAS Registry Number.

A Three-Component Derivatization Protocol for Determining the Enantiopurity of Sulfinamides by 1H and 19F NMR Spectroscopy

Groleau, Robin R.,Chapman, Robert S. L.,Ley-Smith, Harry,Liu, Liyuan,James, Tony D.,Bull, Steven D.

, p. 1208 - 1215 (2020/01/02)

A practically simple three-component chiral derivatization protocol has been developed to determine the enantiopurity of eight S-chiral sulfinamides by 1H and 19F NMR spectroscopic analysis, based on their treatment with a 2-formylphenylboronic acid template and enantiopure pinanediol to afford a mixture of diastereomeric sulfiniminoboronate esters whose diastereomeric ratio is an accurate reflection of the enantiopurity of the parent sulfinamide.
