125453-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125453-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,5 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125453-30:
(8*1)+(7*2)+(6*5)+(5*4)+(4*5)+(3*3)+(2*3)+(1*0)=107
107 % 10 = 7
So 125453-30-7 is a valid CAS Registry Number.

Benzotriazole-Assisted Synthesis of Monoacyl Aminals and Their Peptide Derivatives
Katritzky, Alan R.,Urogdi, Laszlo,Mayence, Annie
, p. 2206 - 2214 (2007/10/02)
Adducts 8-11, derived from benzotriazole (7), an aldehyde (6), and an amide (5), react with ammonia to give various monoacylated aminals (12-14) and "gem-peptide" derivatives (15) in a novel, convenient route, useful for peptide analogue syntheses and stu
