Check Digit Verification of cas no

The CAS Registry Mumber 61781-59-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,8 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 61781-59:
(7*6)+(6*1)+(5*7)+(4*8)+(3*1)+(2*5)+(1*9)=137
137 % 10 = 7
So 61781-59-7 is a valid CAS Registry Number.

Benzopyrones. Part 17. The Synthesis of some Bischromones and the Reaction of Cyanomethyl Esters with Sodium Azide

Bevan, Peter S.,Ellis, Gwynn P.,Wilson, H. Kerr

, p. 2552 - 2556 (1981)

Treatment of 4-oxochromen-2-carboxyl chloride with dimethylcadmium gave 1-methyl-1-(4-oxochromen-2-yl)ethyl 4-oxochromen-2-carboxylate (11) which was synthesized unequivocally and degraded to the carboxylic acid and 2-(1-methylvinyl)chromen-4-one. 2-Acetylchromen-4-one was synthesized by a new and more efficient method from 4-oxochromen-2-carbonyl chloride.The synthesis and some reactions of 4-oxochromen-2-yl isocyanate, and the cyanomethyl esters of 4-oxochromen-2-carboxylic and -2,6-dicarboxylic acids are descibed.
