Check Digit Verification of cas no

The CAS Registry Mumber 127629-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,2 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 127629-33:
(8*1)+(7*2)+(6*7)+(5*6)+(4*2)+(3*9)+(2*3)+(1*3)=138
138 % 10 = 8
So 127629-33-8 is a valid CAS Registry Number.

SPIRO-DIHYDROFURAN-PYRAZOLIDINONES FROM TETRAACETYLETHYLENE AND AZO-DICARBONYL COMPOUNDS

Celli, A. M.,Donati, D.,Scotton, M.

, p. 7929 - 7938 (1989)

Tetraacetylethylene (1) reacted with electron-withdrawing azo compounds to give spiro furan-pyrazoles.Their structure was confirmed by an X-ray crystallographic analysis on a derivative of the spirotriazole-1',3',6'-trione>.The cycloadducts show ring-open chain tautomerism.
