Check Digit Verification of cas no

The CAS Registry Mumber 1045730-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,7,3 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1045730-67:
(9*1)+(8*0)+(7*4)+(6*5)+(5*7)+(4*3)+(3*0)+(2*6)+(1*7)=133
133 % 10 = 3
So 1045730-67-3 is a valid CAS Registry Number.

Studies on the synthesis of valienamine and 1-epi-valienamine starting from d-glucose or l-sorbose

Cumpstey, Ian,Gehrke, Sebastian,Erfan, Sayeh,Cribiu, Riccardo

, p. 1675 - 1692 (2008/12/21)

Two synthetic routes to a carbocyclic precursor to valienamine are reported, starting from either d-glucose or l-sorbose and using ring-closing metathesis as a key step. A low-yielding synthesis of 1-epi-valienamine is reported. Results from an abortive third possible route to valienamine based on an early introduction of nitrogen are discussed.
