81703-97-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81703-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,0 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81703-97:
(7*8)+(6*1)+(5*7)+(4*0)+(3*3)+(2*9)+(1*7)=131
131 % 10 = 1
So 81703-97-1 is a valid CAS Registry Number.

Synthesis of a Trisaccharide related to the Antitumor Antibiotic, Aclacinomycin A
Martin, Alain,Pais, Mary,Monneret, Claude
, p. 305 - 306 (2007/10/02)
Trisaccharide (14), closely related to the trisaccharide moiety of aclacinomycin A has been synthesized stereoselectively by coupling (3) and (5) under Koenigs-Knorr conditions and then (7) and (9) in the presence of N-iodosuccinimide.
