634616-23-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 634616-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,6,1 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 634616-23:
(8*6)+(7*3)+(6*4)+(5*6)+(4*1)+(3*6)+(2*2)+(1*3)=152
152 % 10 = 2
So 634616-23-2 is a valid CAS Registry Number.

Synthesis of polyoxygenated dibenzo[a,e]cycloheptatrienes

Chan, Chieh-Kai,Chan, Yi-Ling,Tsai, Yu-Lin,Chang, Meng-Yang

, p. 2074 - 2088 (2017/03/17)

A successive route for the synthesis of substituted dibenzo[a,e]cycloheptatriene 1 was established by the reduction of 2-allylbenzaldehyde 4, the BF3·OEt2-mediated intermolecular coupling of 2-allylphenylmethanol 5 with oxygenated be

Synthesis of dibenzo-fused 10-membered cyclic ethers from isovanillin Via ring-closing metathesis
