Check Digit Verification of cas no
The CAS Registry Mumber 129738-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,3 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129738-34:
(8*1)+(7*2)+(6*9)+(5*7)+(4*3)+(3*8)+(2*3)+(1*4)=157
157 % 10 = 7
So 129738-34-7 is a valid CAS Registry Number.

2-OXETANONE DERIVATIVE AND PROCESS FOR PRODUCTION THEREOF
-
Page/Page column 14, (2009/03/07)
An aldehyde derivative represented by the general formula (2) is reacted with ketene in the presence of a Lewis acid catalyst to produce a novel 2-oxetanone derivative (1), which is then purified to a 2-oxetanone derivative having a high trans-isomer puri
