Check Digit Verification of cas no

The CAS Registry Mumber 62054-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,0,5 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 62054-41:
(7*6)+(6*2)+(5*0)+(4*5)+(3*4)+(2*4)+(1*1)=95
95 % 10 = 5
So 62054-41-5 is a valid CAS Registry Number.

Intramolecular Anionic Friedel-Crafts Equivalents. An Expeditious Synthesis of 4H-1,2-Benzothiazin-4-one 1,1-Dioxides from N-Arylsulfonylated Amino Acids

Bakker, Wouter I. Iwema,Familoni, O. B.,Padfield, James,Snieckus, Victor

, p. 1079 - 1080 (2007/10/03)

Treatment of compounds 1, readily available from amino acids, with excess LDA furnishes benzothiazinones 2 in modest to good yields (Table); variations of carbanion-mediated reactions lead to benzothiazepinones (Table, entries 12 and 13) and dibenzothiazepinone (5).
