Check Digit Verification of cas no

The CAS Registry Mumber 220307-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,0 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 220307-56:
(8*2)+(7*2)+(6*0)+(5*3)+(4*0)+(3*7)+(2*5)+(1*6)=82
82 % 10 = 2
So 220307-56-2 is a valid CAS Registry Number.

Synthesis of some novel pharmacologically active schiff bases using microwave method and their derivatives formazans by conventional method

Desai, Krunal G.,Desai

, p. 2097 - 2101 (2007/10/03)

Condensation of p-nitrobenzoylhydrazide 1 with substituted aromatic aldehydes 2 under microwave irradiation and by conventional method provide Schiff bases 3a-j. Schiff bases 3a-j on condensation with diazonium salt of 6-methoxy-2-aminobenzothiazole give formazans 4a-j. This reaction is carried out only by conventional method.
