Check Digit Verification of cas no

The CAS Registry Mumber 134671-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,7 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134671-58:
(8*1)+(7*3)+(6*4)+(5*6)+(4*7)+(3*1)+(2*5)+(1*8)=132
132 % 10 = 2
So 134671-58-2 is a valid CAS Registry Number.

scheme or table, p. 141 - 146 (2012/06/18)

Hydrazones are an important class of compounds found in many synthetic products. Due to their importance in synthetic chemistry, the present article reports the synthesis of a new series of ten compounds based on the coupling of 2-oxo-3(2H)-benzothiazoleacetic acid, hydrazide and 2-thioxo-3(2H)- -benzothiazoleacetic acid, hydrazide with different aldehydes. The structures of the synthesized compounds were confirmed by elemental analyses, IR, 1H- -NMR, 13C-NMR and FAB+-MS spectral data. Copyright 2012 (CC) SCS.
