688321-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 688321-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,3,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 688321-38:
(8*6)+(7*8)+(6*8)+(5*3)+(4*2)+(3*1)+(2*3)+(1*8)=192
192 % 10 = 2
So 688321-38-2 is a valid CAS Registry Number.

Syntheses of sugar-related pyrrolidine derivatives by reductive amination reactions
Pino-Gonzalez,Assiego
, p. 199 - 204 (2007/10/03)
Several pyrrolidine iminosugar derivatives have been stereoselectively synthesised from a chiral keto-epoxyamide, by reductive amination procedures. An unexpected cyanide addition was observed when a mixture of SnCl2 and NaCNBH3 was employed.
