Check Digit Verification of cas no

The CAS Registry Mumber 420108-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,1,0 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 420108-38:
(8*4)+(7*2)+(6*0)+(5*1)+(4*0)+(3*8)+(2*3)+(1*8)=89
89 % 10 = 9
So 420108-38-9 is a valid CAS Registry Number.

Michael, Michael-aldol and Michael-Michael reactions of enolate equivalents of butane-2,3-diacetal protected glycolic acid derivatives

Ley, Steven V.,Dixon, Darren J.,Guy, Richard T.,Rodriguez, Felix,Sheppard, Tom D.

, p. 4095 - 4107 (2005)

Consecutive coupling reactions of butane-2,3-diacetal protected glycolic acid derivatives with Michael acceptors and aldehydes are reported. An enantiopure sample of this building block was used to kinetically resolve a chiral Michael acceptor present as a racemic mixture of enantiomers. The Royal Society of Chemistry 2005.
