Check Digit Verification of cas no

The CAS Registry Mumber 93009-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,0,0 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93009-23:
(7*9)+(6*3)+(5*0)+(4*0)+(3*9)+(2*2)+(1*3)=115
115 % 10 = 5
So 93009-23-5 is a valid CAS Registry Number.

A MILD AND EFFICIENT METHOD FOR THE PREPARATION OF N-TOSYL AMIDES AND LACTAMS

Tanner, David,Somfai, Peter

, p. 613 - 618 (2007/10/02)

N-tosyl amides and lactams can be prepared easily and under mild conditions by the inter- or intramolecular condensation of carboxylic acids and secondary sulfonamides.The coupling reagent used is dicyclohexylcarbodiimide (DCC) in the presence of 4-pyrrolidinopyridine (4-PPY) and the reactions proceed readily, usually in high yield, at room temperature.
