Check Digit Verification of cas no

The CAS Registry Mumber 1220971-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,7 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1220971-41:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*7)+(3*1)+(2*4)+(1*1)=124
124 % 10 = 4
So 1220971-41-4 is a valid CAS Registry Number.

Convenient synthesis of a new series of 3-triazolonyl iminocoumarins

Kammoun, Myriam,Turki, Hamida,Fery-Forgues, Suzanne,El Gharbi, Rachid

, p. 888 - 900 (2010)

3-Cyano-7-diethylamino-N-ethoxycarbonyl-iminocoumarin reacted with different hydrazines as N-nucleophiles to afford, in one step, a new series of 2-N-substituted 3-triazolonyl-iminocoumarins in good yields. In two cases, N-unsubstituted derivatives were also obtained. The structures of all the products obtained were confirmed by infrared, 1H NMR, 13C NMR, and elemental analysis. The optical properties of three of these compounds in dichloromethane and ethanol were reported.
