74844-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74844-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,4 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74844-24:
(7*7)+(6*4)+(5*8)+(4*4)+(3*4)+(2*2)+(1*4)=149
149 % 10 = 9
So 74844-24-9 is a valid CAS Registry Number.

Dimetalation of N-tert-Butylmethacrylamide: A New Synthetic Reagent
Fitt, John J.,Gschwend, Heinz W.
, p. 4257 - 4259 (2007/10/02)
Dimetalation of N-tert-butylmethacrylamide with n-butyllithium gives a reagent equivalent to the dianion of methacrylic acid.Its reaction with various electrophiles and the transformation of certain primary products to α-methylene lactones is exemplified.
