Check Digit Verification of cas no

The CAS Registry Mumber 88419-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,4,1 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 88419-03:
(7*8)+(6*8)+(5*4)+(4*1)+(3*9)+(2*0)+(1*3)=158
158 % 10 = 8
So 88419-03-8 is a valid CAS Registry Number.

RECYCLIZATION REACTIONS. RECYCLIZATIONS OF 3-ACYLMETHYL-2,4-THIAZOLIDINEDIONES BY THE ACTION OF NUCLEOPHILES

Shvaika, O. P.,Korotkikh, N. I.,Chervinskii, A. Yu.,Artemov, V. N.

, p. 1533 - 1543 (2007/10/02)

Four directions were established and investigated in the recyclization of 3-acylmethyl-2,4-thiazolidinediones with the participation of the side chain at the cyclic nitrogen atom and the formation of substituted 2-imidazolones or 2-oxazolones (under the influence of ammonia or hydroxides respectively), 2,5-diarylpyrazines (under the influence of methylamine), 6-monosubstituted or 2,6-disubstituted 4,5-dihydro-1,2,4-triazin-3-ones, and 5-substituted 1-amino-2-imidazolones (under the influence of hydrazine and phenylhydrazine).The directions of recyclization with hydrazines are determined by the stereochemical configuration of the intermediate hydrazones; the E-hydrazones of 3-acylmethyl-2,4-thiazolidenediones are converted into 4,5-dihydro-1,2,4-triazin-3-ones, while the Z izomers are converted into 1-amino-2-imidazolones.
