Check Digit Verification of cas no

The CAS Registry Mumber 121918-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,1 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121918-99:
(8*1)+(7*2)+(6*1)+(5*9)+(4*1)+(3*8)+(2*9)+(1*9)=128
128 % 10 = 8
So 121918-99-8 is a valid CAS Registry Number.

Competitive Intramolecular Cycloaddition and Tandem Cycloaddition/-Sigmatropic Rearrangement Sequence of Allenyl 3-Vinyl-2-cyclohexenyl Ethers: Evidence for Switching of the Reaction Pathway by the Substituent Effects

Hayakawa, Kenji,Aso, Kazuyoshi,Shiro, Motoo,Kanematsu, Ken

, p. 5312 - 5320 (2007/10/02)

The base-catalyzed intramolecular cycloaddition reactions (t-BuOK, t-BuOH, 83 deg C) of variously substituted propargyl 3-vinyl-2-cyclohexenyl ethers have been investigated.The reaction proceeded smoothly via the initial isomerization to the corresponding
