Check Digit Verification of cas no
The CAS Registry Mumber 214342-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,3,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 214342-01:
(8*2)+(7*1)+(6*4)+(5*3)+(4*4)+(3*2)+(2*0)+(1*1)=85
85 % 10 = 5
So 214342-01-5 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.
