Check Digit Verification of cas no

The CAS Registry Mumber 130293-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,9 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130293-09:
(8*1)+(7*3)+(6*0)+(5*2)+(4*9)+(3*3)+(2*0)+(1*9)=93
93 % 10 = 3
So 130293-09-3 is a valid CAS Registry Number.

Aminolysis of sulfinamoyl-esters, -sulfonamides and -sulfones. Thiooxamate and thiourea formation via a sulfine intermediate. Thiophilic or carbophilic reaction?

Baltas,Raouf-Benchekroun,De Blic,Cazaux,Tisnes,Gorrichon,Hussein,Barthelat

, p. 14865 - 14876 (2007/10/03)

The aminolysis process of sulfinamoyl derivatives was investigated with sulfinamoyl esters. An intermediate sulfine was unambiguously evidenced by formation of a Diels-Alder type adduct. The aminolysis leads to final thiooxamate products. A carbophilic addition was suggested for the reaction with secondary amines. With sulfinamoyl, -sulfones and -sulfonamides, a thiourea is formed resulting from a double aminolysis.
