147720-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147720-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,7,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147720-69:
(8*1)+(7*4)+(6*7)+(5*7)+(4*2)+(3*0)+(2*6)+(1*9)=142
142 % 10 = 2
So 147720-69-2 is a valid CAS Registry Number.

Zinc triflate-promoted glycosidation: Synthesis of lipid A disaccharide intermediates
Nakayama,Higashi,Soga,Uoto,Kusama
, p. 2909 - 2912 (1992)
Zinc triflate was found to be superior to the heavy metal salts as a promoter in the Koenigs-Knorr type glycosidation reaction in the synthesis of lipid A disaccharide intermediates. It readily promoted the reaction of a complex glycosyl bromide with a re
