178633-73-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 178633-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,6,3 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 178633-73:
(8*1)+(7*7)+(6*8)+(5*6)+(4*3)+(3*3)+(2*7)+(1*3)=173
173 % 10 = 3
So 178633-73-3 is a valid CAS Registry Number.

Synthesis of cyclic depsipeptides and peptides via direct amide cyclization
Villalgordo, Jose M.,Heimgartner, Heinz
, p. 748 - 766 (2007/10/03)
The 2,2-disubstituted 2H-azirin-3-amines 7 (2,2-disubstituted 3-amino-2H-azirines) were used as amino-acid synthons in the preparation of medium-sized cyclic depsipeptides and peptides derived from salicylic acids 6 and anthranilic acid 19, respectively.
