Check Digit Verification of cas no

The CAS Registry Mumber 1240347-82-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,4 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1240347-82:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*4)+(3*7)+(2*8)+(1*2)=123
123 % 10 = 3
So 1240347-82-3 is a valid CAS Registry Number.

One-pot three-component synthesis of the spiroacenaphthylene derivatives

Saeedi, Mina,Heravi, Majid M.,Beheshtiha, Yahya S.,Oskooie, Hossein A.

, p. 5345 - 5348 (2010)

A facile and efficient one-pot three-component synthesis of the spiroacenaphthylene derivatives was achieved, via the reaction of acenaphthequinone, malononitrile/ethylcyanoacetate and various reagents including a-methylencarbonyl compounds/enols.
