99698-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99698-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,9 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99698-23:
(7*9)+(6*9)+(5*6)+(4*9)+(3*8)+(2*2)+(1*3)=214
214 % 10 = 4
So 99698-23-4 is a valid CAS Registry Number.

ON THE MECHANISM OF THE MANDER CARBOMETHOXYLATION OF KETONE ENOLATES WITH METHYL CYANOFORMATE
Ziegler, Frederick E.,Wang, Tein-Fu
, p. 2291 - 2292 (2007/10/02)
The acylation of lithium enolates of ketones with methyl cyanoformate has been shown to proceed through an aldol-type intermediate that can be trapped at low temperature.
