Check Digit Verification of cas no

The CAS Registry Mumber 87192-07-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,9 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87192-07:
(7*8)+(6*7)+(5*1)+(4*9)+(3*2)+(2*0)+(1*7)=152
152 % 10 = 2
So 87192-07-2 is a valid CAS Registry Number.

Ring Construction Using 3-(Arylmethylene)-2,4(3H,5H)-furandione: Synthesis of Pyrazolones and Furobenzothiazepinones

Grob Schmidt, Diane,Zimmer, Hans

, p. 4367 - 4370 (1983)

The ring transformation of 3-(arylmethylene)-2,4(3H,5H)-furandiones (2) into the corresponding pyrazolones (3) is described.The conversion with selected hydrazines proceeds regioselectively to form a uniquely substituted pyrazolone system (3) as the major
