40682-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40682-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40682-81:
(7*4)+(6*0)+(5*6)+(4*8)+(3*2)+(2*8)+(1*1)=113
113 % 10 = 3
So 40682-81-3 is a valid CAS Registry Number.

, p. 1291 - 1299 (2007/10/02)
The title compounds I-IV with the respective ribo-, arabino-, xylo- and lyxo-configuration were prepared by reaction of 1-O-acetyl-2,3,5-tri-O-benzoyl-D-pentofuranoses with trimethylsilyl cyanide in 1,2-dichloroethane, catalyzed with tin tetrachloride.The
