Check Digit Verification of cas no

The CAS Registry Mumber 118304-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118304-02:
(8*1)+(7*1)+(6*8)+(5*3)+(4*0)+(3*4)+(2*0)+(1*2)=92
92 % 10 = 2
So 118304-02-2 is a valid CAS Registry Number.

Study on the diastereospecificity of diazomethane cycloadditions to substituted 1,2-dihydro naphthalenes

Vebrel, Joel,Tonnard, Francois,Carrie, Robert

, p. 1056 - 1064 (2007/10/02)

The 1,2-dihydro-3-carbomethoxynaphthalenes substituted at the 1 or 2 position by alkyl groups add diazomethane diastereospecifically to give adducts in which the substituent is cis to the ester group.This establishes the importance of conformational facto
