Check Digit Verification of cas no

The CAS Registry Mumber 1261268-15-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,2,6 and 8 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1261268-15:
(9*1)+(8*2)+(7*6)+(6*1)+(5*2)+(4*6)+(3*8)+(2*1)+(1*5)=138
138 % 10 = 8
So 1261268-15-8 is a valid CAS Registry Number.

Synthesis of substituted 1,2-dihydropyridines from propargyl vinyl ethers and allenic vinyl ethers by gold-catalyzed claisen rearrangement and 6π-aza-electrocyclization

Wei, Hao,Wang, Yao,Yue, Bin,Xu, Peng-Fei

supporting information; experimental part, p. 2450 - 2454 (2010/12/25)

An efficient synthetic method was developed for the construction of substituted 1,2-dihydropyridines by gold-catalyzed tandem reactions. The key intermediates 2,4-dienals were generated from propargyl vinyl ethers or allenic vinyl ethers with gold catalys
