252875-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252875-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,8,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 252875-72:
(8*2)+(7*5)+(6*2)+(5*8)+(4*7)+(3*5)+(2*7)+(1*2)=162
162 % 10 = 2
So 252875-72-2 is a valid CAS Registry Number.

A short synthesis of chiral peraza-macrocycles through opening of cyclic sulfamidates
Kim, B. Moon,So, Soon Mog
, p. 7687 - 7690 (2007/10/03)
Efficient and general synthetic methods for novel chiral peraza-macrocycles have been developed. Sequential reactions of the known cyclic sulfamidate 4 derived from N-benzyl-L-serine methyl ester with p-methoxybenzylamine provided a symmetric triamine 3,
