330953-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 330953-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,9,5 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 330953-63:
(8*3)+(7*3)+(6*0)+(5*9)+(4*5)+(3*3)+(2*6)+(1*3)=134
134 % 10 = 4
So 330953-63-4 is a valid CAS Registry Number.

Synthesis of enantiomerically pure morphan analogues from α-d-glucose
Streicher, Benedikt,Wünsch, Bernhard
, p. 115 - 120 (2007/10/03)
The synthesis of the enantiomerically pure morphan analogue 19 starting with the methyl glucopyranoside 6 is described. Homologation, reduction, and acylation provide the heptopyranosamine derivatives 9a-c. After removal of the hydroxy group of 9c the int
