137934-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137934-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,3 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137934-97:
(8*1)+(7*3)+(6*7)+(5*9)+(4*3)+(3*4)+(2*9)+(1*7)=165
165 % 10 = 5
So 137934-97-5 is a valid CAS Registry Number.

Acid Catalyzed Alcoholysis of an Epoxide and Reactions of Products on Contact with Silica Gel
Habermehl, Gerhard G.,Wippermann, Irene
, p. 1421 - 1424 (2007/10/02)
The alcoholysis of epoxide 1 in acidic methanol leads to various products; one of these - hydroxymethoxyketone 7 - rearranges to the isomeric ketone 14 on contact with silica gel. Keywords: Cleavage of Epoxide, Rearrangement
