118429-39-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118429-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,2 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118429-39:
(8*1)+(7*1)+(6*8)+(5*4)+(4*2)+(3*9)+(2*3)+(1*9)=133
133 % 10 = 3
So 118429-39-3 is a valid CAS Registry Number.

, p. 867 - 870 (2007/10/02)
Catalytic decomposition of 1-diazo-4-tosylamino-2-butanone 1a, -2-pentanone 1b, and -2-hexanone 1c, results in the quantitative formation of the 1-tosyl-3-pyrrolidinones 2a, 2b and 2c, while the photolysis afforded the rearranged esters, 3a, 3b and 3c, or
