904674-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 904674-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,7 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 904674-30:
(8*9)+(7*0)+(6*4)+(5*6)+(4*7)+(3*4)+(2*3)+(1*0)=172
172 % 10 = 2
So 904674-30-2 is a valid CAS Registry Number.

Inter- and intramolecular glycosylation of exo-glycals promoted by metallic Lewis acids
Hsu, Sheng-Jie,Lin, Hui-Chang,Lin, Chun-Hung
, p. 1428 - 1437 (2007/10/03)
exo-Glycosyl carbonates were employed for inter- and intramolecular glycosylation reactions. A number of metallic Lewis Acids and solvents were examined to enhance the reactivity. The optimum conditions were found to be the use of AlCl3 in 1-ni
