Check Digit Verification of cas no

The CAS Registry Mumber 1233765-81-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,6 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233765-81:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*6)+(3*5)+(2*8)+(1*1)=155
155 % 10 = 5
So 1233765-81-5 is a valid CAS Registry Number.

Synthesis of (E)-6-alkenylpurines via Pd-catalyzed stannation/ protodestannation tandem process of alkynylpurines

Klecka, Martin,KovacEK, Martin,Tobrman, Toma,Dvoak, Dalimil

experimental part, p. 313 - 332 (2010/08/05)

A methodology for the synthesis of (E)-6-alkenylpurines, starting from 6-iodopurines, based on a Pd-catalyzed stannation/protodestannation protocol, is described. The alkynylation reactions were catalyzed by Pd(OAc) 2/PPh3 in acetonitrile. The Pd-catalyzed stannation itself provided a mixture of Z regioisomers but following protodestannation using TFA induces Z to E isomerization giving (E)-6-alkenylpurines. The reactivity of other 2-and 8-alkynyl purines has also been studied.
