Check Digit Verification of cas no

The CAS Registry Mumber 547769-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,7,7,6 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 547769-33:
(8*5)+(7*4)+(6*7)+(5*7)+(4*6)+(3*9)+(2*3)+(1*3)=205
205 % 10 = 5
So 547769-33-5 is a valid CAS Registry Number.

A short and common stereoselective approach to 5/6, 6/6, 6/7 bicyclic aza sugars

Chandrasekhar,Venkateswara Rao,Veera Mohana Rao,Jagadeesh

experimental part, p. 1217 - 1223 (2009/12/01)

An efficient and highly stereoselective approach to bicyclic aza sugars is described using Grignard reaction on an N-benzyl imine derived from 3-O-benzyl-1,2-O-isopropylidine-α-d-xylo-pentodialdofuranose, ring closing metathesis, and reductive cyclization
