Check Digit Verification of cas no

The CAS Registry Mumber 73373-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,3,7 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73373-12:
(7*7)+(6*3)+(5*3)+(4*7)+(3*3)+(2*1)+(1*2)=123
123 % 10 = 3
So 73373-12-3 is a valid CAS Registry Number.

STAGES OF THE CONDENSATION OF 1,4-BUTANEDIOL IN THE MARKOVNIKOV - GUERBET REACTION

Lyubomilov, V. I.,Slesareva, L. A.,Pshenitsyna, V. P.,Slonim, I. Ya.,Bulai, A. Kh.

, p. 1871 - 1874 (2007/10/02)

The condensation of 1,4-butanediol in the presence of its sodium alcoholate and Ni/Cr2O3 leads to the formation of 4-hydroxybutanal and, from the latter, 3-formyl-1,4,7-heptanetriol.The latter exists in equilibrium with 1,7-dihydroxy-3-hydroxymethyl-4-heptanone and 2-hydroxy-2-(1-hydroxymethyl-3-hydroxypropyl)tetrahydrofuran.Dehydration of the latter with the formation of an endocyclic double bond and subsequent isomerization and reduction processes lead to the production of 2-(1-hydroxymethyl-3-hydroxypropyl)tetrahydrofuran.
