The CAS Registry Mumber 134828-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134828-47:
(8*1)+(7*3)+(6*4)+(5*8)+(4*2)+(3*8)+(2*4)+(1*7)=140
140 % 10 = 0
So 134828-47-0 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF 1-ARYL-1,4-DIHYDRO-2,7-DIMETHYL-4-OXOPYRIDOPYRIMIDINE-6-CARBOXYLIC ACIDS AND THEIR DERIVATIVES

Deyanov, A. B.,Gavrilov, M. Yu.,Konshin, M. E.

, p. 449 - 453 (2007/10/02)

Acetylation of 2-arylamino-5-carbethoxy-6-methylnicotinonitriles gave N-acetyl-2-arylamino-5-carbethoxy-6-methylnicotinonitriles, which, under the influence of hydrogen chloride, are cyclized to 1-aryl-1,4-dihydro-6-carbethoxy-2,7-dimethyl-4-oxopyridopyrimidines.The latter can be converted to the corresponding carboxylic and hydroxamic acids, as well as to acetylation products 1-aryl-2-acetonyl-1,4-dihydro-6-carbethoxy-7-methyl-4-oxopyridopyrimidines.
