Check Digit Verification of cas no

The CAS Registry Mumber 90301-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90301-25:
(7*9)+(6*0)+(5*3)+(4*0)+(3*1)+(2*2)+(1*5)=90
90 % 10 = 0
So 90301-25-0 is a valid CAS Registry Number.

New chiral building blocks and branched 1,6-anhydro sugars from regio- and stereoisomeric Cerny epoxides

Krohn, Karsten,Gehle, Dietmar,Floerke, Ulrich

, p. 4557 - 4562 (2007/10/03)

The tandem epoxide→allyl alcohol rearrangement-cuprate cross-coupling previously described for the Cerny epoxide 1, to yield the allyl alcohol 2, was extended to the regioisomeric epoxy-tosylate 3, to yield allyl alcohol 4, and to the stereoisomeric epoxi
