122665-69-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122665-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,6 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122665-69:
(8*1)+(7*2)+(6*2)+(5*6)+(4*6)+(3*5)+(2*6)+(1*9)=124
124 % 10 = 4
So 122665-69-4 is a valid CAS Registry Number.

Synthesis of aryl- and vinyl-sydnones. Cross-coupling of 4-copper-3-phenylsydnone with aryl and vinyl halides catalyzed by palladium(0) complexes
Kalinin, V. N.,Min, She Fan
, p. C34 - C36 (1988)
A general method is suggested for introduction of substituents into the 4-position of 3-phenylsydnone by palladium(0) catalyzes cross-coupling of 4-copper-3phenyl-sydnone with aryl iodides and vinyl bromides.
