Check Digit Verification of cas no

The CAS Registry Mumber 74306-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,0 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74306-99:
(7*7)+(6*4)+(5*3)+(4*0)+(3*6)+(2*9)+(1*9)=133
133 % 10 = 3
So 74306-99-3 is a valid CAS Registry Number.

Morita, Tadayoshi,Karasawa, Michito,Takase, Kahei

, p. 197 - 200 (2007/10/02)

1,2-Azulenequinones (1,2-azulenediones) (1a-c) were synthesized by dehydrogenation of the corresponding 1,2-dihydroxyazulenes (5a-c) which were prepared from 2-acetoxyazulenes (2b,c) by benzoyloxylation followed by hydrolysis.Some chemical and physical properties of 1a-c are also described.
