Check Digit Verification of cas no

The CAS Registry Mumber 129193-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,9 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129193-15:
(8*1)+(7*2)+(6*9)+(5*1)+(4*9)+(3*3)+(2*1)+(1*5)=133
133 % 10 = 3
So 129193-15-3 is a valid CAS Registry Number.

STEREOCHEMICAL STUDIES, 144. SATURATED HETEROCYCLES, 151. PREPARATION OF cis AND trans-CYCLOALKANE-CONDENSED PYRIMIDINEDIONES BY AZETIDINONE RING TRANSFORMATION

Stajer, Geza,Szoeke-Molnar, Zsolt,Bernath, Gabor,Sohar, Pal

, p. 1943 - 1950 (2007/10/02)

N-substituted derivatives (3 and 4) obtained from cyclopentane- and cyclohexane-azetidinones (1 and 2) were isomerized with polyphosphoric acid to give cyclopentane-cis- (6) and cyclohexane-trans-condensed (7) 2,4-pyrimidinediones.The structures of the dihydrouracils prepared by the ring transformation were proved by 1H- and 13C-nmr spectroscopy and by comparison with the compounds synthesized from cis- and trans-2-amino-1-cycloalkanecarboxamides (11-13) with 1,1'-carbonyldiimidazole.
