Check Digit Verification of cas no

The CAS Registry Mumber 132664-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,6,6 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 132664-74:
(8*1)+(7*3)+(6*2)+(5*6)+(4*6)+(3*4)+(2*7)+(1*4)=125
125 % 10 = 5
So 132664-74-5 is a valid CAS Registry Number.

REGIO- AND STEREODIRECTIVITY IN THE REACTIONS OF ISOQUINOLINIUM YLIDES WITH UNSATURATED NITRILES

Shestopalov, A. M.,Rodinovskaya, L. A.,Sharanin, Yu. A.,Litvinov, V. P.

, p. 2348 - 2353 (2007/10/02)

Reactions of isoquinolinium ylides with arylmethylenemalonitriles involve 1,3-dipolar cycloaddition, with the highly regio- and stereoselective formation of 2-aryl-3-benzoyl(or carbamoyl)-1,1-dicyano-2,3-trans-1,2,3,10b-tetrahydropyrroloisoquinolines.In contrast, N-phenacylisoquinolinium ylide reacts with arylmethylenecyanothioacetamides differently, proceeding regio- and stereoselectively to give 4-aryl-2-hydroxy-3-(1-isoquinolinio)-2-phenyl-3-cyano-3,4-trans-1,2,3,4-tetrahydropyridine-6-thiolates.
