Check Digit Verification of cas no
The CAS Registry Mumber 220497-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,9 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220497-94:
(8*2)+(7*2)+(6*0)+(5*4)+(4*9)+(3*7)+(2*9)+(1*4)=129
129 % 10 = 9
So 220497-94-9 is a valid CAS Registry Number.

A Synthetic Approach to Neplanocin A and Queuosine: Unusual Natural Nucleosides Containing Cyclopentenyl Rings
Fang, Jim-Min,Cherng, Yie-Jia
, p. 1568 - 1577 (2007/10/02)
A general method is provided for the preparation of 1β-(methoxycarbonylamino)-2α,3α-(dimethylmethylenedioxy)-4-hydroxymethyl-4-cyclopentene (11) and 1β-amino-2α,3α-(dimethylmethylenedioxy)-4-cyclopentene (15), which are key intermediates for synthesis of natural cyclopentenoidal nucleosides, neplanocin A and queuosine.
