77022-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77022-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,2 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77022-24:
(7*7)+(6*7)+(5*0)+(4*2)+(3*2)+(2*2)+(1*4)=113
113 % 10 = 3
So 77022-24-3 is a valid CAS Registry Number.

REACTION OF PYRIDINIUM DISUBSTITUTED METHYLIDES WITH DIPHENYLCYCLOPROPENETHIONE
Matsumoto, Kiyoshi,Ikemi, Yukio
, p. 1445 - 1448 (2007/10/02)
Diphenylcyclopropenethione undergoes nucleophilic attack by pyridinium disubstituted ylides (1a-e) to produce the corresponding indeno-2-thiopyrone (3), 2-pyrone (5 or 10), 1-thio-2-pyrone (6, 8, 11 or 12), and/or 2-thiopyrone (4) derivatives.
