Check Digit Verification of cas no

The CAS Registry Mumber 91851-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,5 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91851-05:
(7*9)+(6*1)+(5*8)+(4*5)+(3*1)+(2*0)+(1*5)=137
137 % 10 = 7
So 91851-05-7 is a valid CAS Registry Number.

The Reaction of Phenylglyoxal with Primary Aliphatic and Aromatic Amines. Synthesis of Phenylglyoxal Monoimines and some Derivatives.

Alcaide, Benito,Escobar, Gerardo,Perez-Ossorio, Rafael,Plumet, Joaquin,Sanz, Dionisia

, p. 1466 - 1488 (2007/10/02)

Condensation of phenylglyoxal with primary aliphatic amines yields the related keto-aldimines.When primary aromatic amines are used, aldimines, amino-hydroxy-ketones, diamino-ketones, and alkoxy-amino-ketones are obtained depending upon the nature of the amine and the experimental conditions.Alternatively the monoimines can be obtained by dehydration of C-hydroxyphenacylarylamines and by demethanolation of C-methoxyphenacylarylamines both on treatment with Pd/C catalyst.Reduction of phenylglyoxal monoimines with sodium borohydride yielded H-substituted 1-phenyl-2-aminoethanols and 1,3-dipolar cycloaddition of the imines with p-chlorobenzonitrile oxide afforded 4-substituted 5-benzoyl-3-(p-chlorophenyl)-4,5-dihydro-1,2,4-oxadiazoles.
