Check Digit Verification of cas no
The CAS Registry Mumber 129083-15-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,8 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129083-15:
(8*1)+(7*2)+(6*9)+(5*0)+(4*8)+(3*3)+(2*1)+(1*5)=124
124 % 10 = 4
So 129083-15-4 is a valid CAS Registry Number.

Asymmetric synthesis of (+)-1-deoxynojirimycin
Lindstroem, Ulf M.,Somfai, Peter
, p. 7173 - 7176 (2007/10/03)
An asymmetric synthesis of (+)-1-deoxynojirimycin (1) in 14 steps starting from diene (5) is described. The key transformations in the sequence are a sharpless dihydroxylation and epoxidation followed by a regio- and stereoselective aminolysis of vinyl epoxide 11 to give piperidine 12.
