Check Digit Verification of cas no

The CAS Registry Mumber 1277186-28-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,1,8 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1277186-28:
(9*1)+(8*2)+(7*7)+(6*7)+(5*1)+(4*8)+(3*6)+(2*2)+(1*8)=183
183 % 10 = 3
So 1277186-28-3 is a valid CAS Registry Number.

Enantioselective construction of bridged multicyclic skeletons: Intermolecular [2+2+2] cycloaddition/intramolecular diels-alder reaction cascade

Kobayashi, Masayuki,Suda, Takeshi,Noguchi, Keiichi,Tanaka, Ken

supporting information; experimental part, p. 1664 - 1667 (2011/03/22)

Bridging a gap: A cationic rhodium(I)/ligand complex catalyzes the title reaction of alkynes and amide-linked 1,5-dienes, leading to bridged multicyclic compounds, with high chemo-, regio-, and enantioselectivity (see scheme; Bn=benzyl).
