Check Digit Verification of cas no

The CAS Registry Mumber 880135-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,1,3 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 880135-57:
(8*8)+(7*8)+(6*0)+(5*1)+(4*3)+(3*5)+(2*5)+(1*7)=169
169 % 10 = 9
So 880135-57-9 is a valid CAS Registry Number.

Stereoselective synthesis of tricyclic pyranoxepin derivatives by ruthenium-catalyzed enyne metathesis/Diels-Alder reaction

Majumdar,Rahaman,Muhuri,Roy

, p. 466 - 468 (2007/10/03)

Synthesis of tricyclic oxepin-annulated pyrone derivatives has been achieved by the ring-closing enyne metathesis using the first-generation Grubbs' catalyst under a nitrogen atmosphere. The Diels-Alder reaction of these cyclized products with the dienoph
