The CAS Registry Mumber 135370-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,7 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135370-45:
(8*1)+(7*3)+(6*5)+(5*3)+(4*7)+(3*0)+(2*4)+(1*5)=115
115 % 10 = 5
So 135370-45-5 is a valid CAS Registry Number.

ACID-CATALYZED ACYLATION OF 4-ALKYL-3-AZAPYRYLIUM SALTS AND THE SYNTHESIS OF 4-ACYLAMINOPYRYLIUM SALTS

Shibaeva, N. V.,Borodaev, S. V.,Yudilevich, I. A.,Knyazev, A. P.,Dubonosov, A. D.,et al.

, p. 219 - 223 (1991)

4-Alkyl-3-azapyrylium salts undergo acylation at the alkyl group under acid-catalyzed conditions to give 4-acylmethyl-3-azapyrylium derivatives, which upon heating in proton-donating solvents recyclize to give 4-acylaminopyrylium salts.
