Check Digit Verification of cas no

The CAS Registry Mumber 122278-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,7 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 122278-07:
(8*1)+(7*2)+(6*2)+(5*2)+(4*7)+(3*8)+(2*0)+(1*7)=103
103 % 10 = 3
So 122278-07-3 is a valid CAS Registry Number.

ENYNONES IN ORGANIC SYNTHESIS. I. SPIROANNULATION BY TANDEM OXY-COPE REARRANGEMENT-ELECTROCYCLIC RING CLOSURE

Jacobi, Peter A.,Armacost, Lisa M.,Kravitz, Joseph I.,Martinelli, Michael J.,Selnick, Harold G.

, p. 6865 - 6868 (1988)

Bis-acetylenic alcohols of proper design undergo a facile oxy-Cope rearrangement to afford mixtures of E- and Z-enynones.These latter compounds afford methylenecyclopentenones upon enolization and electrocyclic ring closure.
