Check Digit Verification of cas no

The CAS Registry Mumber 204581-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,8 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 204581-50:
(8*2)+(7*0)+(6*4)+(5*5)+(4*8)+(3*1)+(2*5)+(1*0)=110
110 % 10 = 0
So 204581-50-0 is a valid CAS Registry Number.

Stereochemical course of acylation and aldol condensation in (4S)-4-methyl-2-benzyl-2,4-dihydro-1H-pyrazino[2,1-b]quinazoline-3,6-diones

Bartolome, M. Teresa,Buenadicha, Felix L.,Avendano, Carmen,Soellhuber, Monica

, p. 249 - 258 (2007/10/03)

Acylation of 1 leads to the syn derivatives 2. Traces of the anti isomers equilibrate to the syn isomers when stored in CHCl3. Aldol condensation showed great diastereoselectivity, but racemization could not be avoided. The configuration of the
