Check Digit Verification of cas no

The CAS Registry Mumber 1204388-90-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,3,8 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1204388-90:
(9*1)+(8*2)+(7*0)+(6*4)+(5*3)+(4*8)+(3*8)+(2*9)+(1*0)=138
138 % 10 = 8
So 1204388-90-8 is a valid CAS Registry Number.

Organocatalyzed Tsuji-Trost reaction: a new method for the closure of five- and six-membered rings

Vulovic, Bojan,Bihelovic, Filip,Matovic, Radomir,Saicic, Radomir N.

experimental part, p. 10485 - 10494 (2010/02/28)

A combination of organotransition metal catalysis and organocatalysis allows for Tsuji-Trost 5-exo- and 6-exo-cyclizations of aldehydes. This transformation can also be accomplished as a catalytic asymmetric reaction, which affords vinylcyclopentane deriv
