Check Digit Verification of cas no

The CAS Registry Mumber 84725-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,2 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 84725-12:
(7*8)+(6*4)+(5*7)+(4*2)+(3*5)+(2*1)+(1*2)=142
142 % 10 = 2
So 84725-12-2 is a valid CAS Registry Number.

SYNTHESIS AND CATALYTIC HYDROGENATION OF 5-OXOTETRAHYDRO-4H-CHROMENES

Kharchenko, V. G.,Markova, L. I.,Smirnova, N. S.,Korshunova, K. M.,Rybina, G. I.

, p. 1926 - 1930 (2007/10/02)

A systematic investigation was undertaken into the intramolecular heterocyclization of 2-(3-oxopropyl)-1,3-cyclohexanediones by the action of chemical reagents.It was established that the direction of the heterocyclization reactions depends on the structure of the initial compound, the temperature, and the cyclizing agent.It was shown that the investigated compounds can undergo cyclization with the formation of 5-oxo-5,6,7,8-tetrahydro-4H-chromenes, which are capable of being converted into hexahydrochromans and 5-oxo-1-oxabicyclodec-9-enes under the conditions of catalytic hydrogenation.
