130894-64-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130894-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,9 and 4 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130894-64:
(8*1)+(7*3)+(6*0)+(5*8)+(4*9)+(3*4)+(2*6)+(1*4)=133
133 % 10 = 3
So 130894-64-3 is a valid CAS Registry Number.

SYMMETRIE-ENHANCED REMOTE DICARBANION ANNULATIONS FOR LATENT CYCLOALKENONES: APPLICATION TO ALKALOIDS AND TERPENES
Lansbury, Peter T.,Spagnuolo, Ciro J.,Grimm, Erich L.
, p. 3965 - 3968 (2007/10/02)
Fuctionalized 1,n-dicarbanions (n = 4,5,6) react with α,α'-methallyl dihalides to produce n+3 substituted α-methylenecycloalkanes that are synthetic equivalents of two differentiable cycloalkenones.
