Check Digit Verification of cas no
The CAS Registry Mumber 20296-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,9 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20296-69:
(7*2)+(6*0)+(5*2)+(4*9)+(3*6)+(2*6)+(1*9)=99
99 % 10 = 9
So 20296-69-9 is a valid CAS Registry Number.

PALLADIUM CATALYZED COUPLING OF ORGANOSTANNANES WITH VINYL EPOXIDES
Tueting, David R.,Echavarren, Antonio M.,Stille, J. K.
, p. 979 - 992 (2007/10/02)
The coupling reaction of organotin reagents with vinyl epoxides, catalyzed by palladium, takes place at ambient temperatures, regioselectively, giving predominately the 1,4-addition product.Both aryl- and vinylstannanes undergo coupling in high yields, wh
