Check Digit Verification of cas no

The CAS Registry Mumber 1286254-55-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,5 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1286254-55:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*5)+(3*4)+(2*5)+(1*5)=174
174 % 10 = 4
So 1286254-55-4 is a valid CAS Registry Number.

A palladium-catalyzed three-component cross-coupling of conjugated dienes or terminal alkenes with vinyl triflates and boronic acids

Liao, Longyan,Jana, Ranjan,Urkalan, Kaveri Balan,Sigman, Matthew S.

supporting information; experimental part, p. 5784 - 5787 (2011/06/10)

A three-component coupling of vinyl triflates and boronic acids to alkenes catalyzed by palladium is reported. Using 1,3-dienes, selective 1,2-alkene difunction-alization is observed, whereas the use of terminal alkenes results in 1,1-alkene difunctionalization. The reaction outcome is attributed to the formation of stabilized, cationic Pd-π-allyl intermediates to regulate β-hydride elimination.
