118650-57-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118650-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,6,5 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 118650-57:
(8*1)+(7*1)+(6*8)+(5*6)+(4*5)+(3*0)+(2*5)+(1*7)=130
130 % 10 = 0
So 118650-57-0 is a valid CAS Registry Number.

SYNTHESIS OF 3-, 4-, AND 6-MONODEOXYSUCROSES
Descotes, Gerard,Mentech, Julio,Roques, Nathalie
, p. 63 - 70 (2007/10/02)
A divergent synthesis of 6-deoxy (5), 4-deoxy (9), and 3-deoxy (15) derivatives of sucrose, after acetalation of sucrose with 2,2-dimethoxypropane, is detailed.Thus, 5 was prepared by hydrogenolysis of 6-S-(2-pyridyl)-6-thiosucrose, whereas 9 and 15 were obtained by radical reduction of the corresponding thiocarbonyl derivatives.
