109953-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109953-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,5 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109953-83:
(8*1)+(7*0)+(6*9)+(5*9)+(4*5)+(3*3)+(2*8)+(1*3)=155
155 % 10 = 5
So 109953-83-5 is a valid CAS Registry Number.

PREPARATION OF (+/-)-α-ALKYLATED AMINO ACID DERIVATIVES VIA IMIDAZOLES
Lipshutz, Bruce H.,Huff, Bret,Vaccaro, Wayne
, p. 4241 - 4244 (2007/10/02)
Photooxidation of N-methoxy-2,4-disubstituted imidazoles, readily available by way of a three component cyclization followed by O-alkylation, leads to stable acylimines which react with various organomethalics to afford α, α-disubstituted amino acid bis-a
