123791-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123791-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,9 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123791-74:
(8*1)+(7*2)+(6*3)+(5*7)+(4*9)+(3*1)+(2*7)+(1*4)=132
132 % 10 = 2
So 123791-74-2 is a valid CAS Registry Number.

Successive treatment of epoxypropionylpyrazolines with N-bromosuccinimide in chloroform and triethylamine in acetone affords 5-hydroxy-4-oxo-3-arylpyrrolidino-pyrazoles, which are oxygenated derivatives of the alkaloid withasomnine.The reaction pro
