Check Digit Verification of cas no

The CAS Registry Mumber 93261-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,6 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 93261-38:
(7*9)+(6*3)+(5*2)+(4*6)+(3*1)+(2*3)+(1*8)=132
132 % 10 = 2
So 93261-38-2 is a valid CAS Registry Number.

Ultrasound-assisted synthesis of azlactone and its reactions with nucleophiles

Paponov, Boris V.,Lvov, Sergey V.,Ichetovkina, Ekaterina V.,Panasenko, Ilya A.,Stepanian, Stepan G.

, p. 273 - 274 (2012)

4-(2-Oxoindolin-3-ylidene)-2-phenyl-5(4H)-oxazolone (azlactone) was synthesized as a mixture of E- and Z-isomers by ultrasound-assisted Erlenmeyer-Pl?chl reaction between isatin and N-benzoylglycine. Treatment of azlactone with nucleophiles causes opening of its oxazolone moiety.
