Check Digit Verification of cas no

The CAS Registry Mumber 142501-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,0 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142501-65:
(8*1)+(7*4)+(6*2)+(5*5)+(4*0)+(3*1)+(2*6)+(1*5)=93
93 % 10 = 3
So 142501-65-3 is a valid CAS Registry Number.

Gruttadauria, Michelangelo,Buccheri, Francesco,Buscemi, Silvestre,Cusmano, Giuseppe,Noto, Renato,Werber, Giuseppe

, p. 233 - 236 (2007/10/02)

The photochemical behaviour of some substituted aldehyde thiosemicarbazones 1a-k has been investigated in methanol at 254 nm.Thiosemicarbazones of glyoxil methyl ester 1a-f cyclized to furnish the 3-thioxo-1,2,4-triazin-5-one 2-ring system.The remaining thiosemicarbazones 1g-j gave 1,2,4-triazoline 4-derivatives.
