Check Digit Verification of cas no

The CAS Registry Mumber 73733-02-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,3 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73733-02:
(7*7)+(6*3)+(5*7)+(4*3)+(3*3)+(2*0)+(1*2)=125
125 % 10 = 5
So 73733-02-5 is a valid CAS Registry Number.

TRANSFORMATIONS OF o-NAPHTHOQUINONE DIAZIDES IN ALIPHATIC ALCOHOLS

Ponomareva, R. P.,Komagorov, A. M.,Andronova, N. A.

, p. 140 - 149 (2007/10/02)

During photodecomposition and thermal decomposition in hydroxyl-containing media (alcohols, water) o-naphthoquinone diazides in electronically excited and vibrationally excited states eliminate nitrogen, forming the corresponding ketocarbenes.The singlet ketocarbenes undergo intramolecular transformation (with ring contraction and the formation of 3-indenecarboxylic acid or its esters) and intermolecular transformation, forming 1,2-hydroxyalkoxynaphthalenes in reaction with alcohols.The triplet ketocarbenes undergo intermolecular transformations, forming 1- or 2-hydroxynaphthalenes.The composition and ratio of the final products from the decomposition of o-naphthoquinone diazides in alcohols depend significantly on the nature of the alcohol, the presence of oxygen, the presence of radical acceptors, and the spectral composition of the exciting light.
