531515-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 531515-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,1,5,1 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 531515-01:
(8*5)+(7*3)+(6*1)+(5*5)+(4*1)+(3*5)+(2*0)+(1*1)=112
112 % 10 = 2
So 531515-01-2 is a valid CAS Registry Number.

Somfai, Peter,Marchand, Patrice,Torsell, Staffan,Lindstr?m, Ulf M.
, p. 1293 - 1299 (2003)
Asymmetric total syntheses of (+)-1-deoxynojirimycin (1) and (+)-castanospermine (2) are described. Starting from diene 3, the required absolute stereochemistry is introduced by an asymmetric hydroxylation followed by epoxidation. An intramolecular cycliz
