Check Digit Verification of cas no

The CAS Registry Mumber 73045-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,4 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73045-72:
(7*7)+(6*3)+(5*0)+(4*4)+(3*5)+(2*7)+(1*2)=114
114 % 10 = 4
So 73045-72-4 is a valid CAS Registry Number.

Synthesis of β-D-Mannopyranosides and β-L-Rhamnopyranosides by Glycosidation at C-1

Srivastava, Vinai K.,Schuerch, Conrad

, p. 1121 - 1126 (2007/10/02)

A stereoselective synthesis of β-D-mannopyranosides and β-L-rhamnopyranosides has been achieved by glycosidation at C-1.Treatment of the 1-O-tosyl derivative 2 with 1 equiv of methanol in acetonitrile gave methyl 3,4,6-tri-O-benzyl-2-O-(methylsulfonyl)-β-
