Check Digit Verification of cas no

The CAS Registry Mumber 142952-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142952-89:
(8*1)+(7*4)+(6*2)+(5*9)+(4*5)+(3*2)+(2*8)+(1*9)=144
144 % 10 = 4
So 142952-89-4 is a valid CAS Registry Number.

Palladium-catalyzed heck couplings of L-vinylglycine derivatives with vinyl and aryl halides and triflates

Crisp, Geoffrey T.,Glink, Peter T.

, p. 3541 - 3556 (2007/10/02)

The coupling of aryl and vinyl halides and triflates with L-vinylglycine derivatives under the influence of a palladium catalyst is described. The coupling is regioselective and stereoselective with the absolute configuration of the α-amino acid centre be
