Check Digit Verification of cas no

The CAS Registry Mumber 684-02-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 684-02:
(5*6)+(4*8)+(3*4)+(2*0)+(1*2)=76
76 % 10 = 6
So 684-02-6 is a valid CAS Registry Number.

Baran, Janusz,Klein, Herbert,Schade, Christian,Will, Elfriede,Koschinsky, Rainer,et al.

, p. 2181 - 2184 (1988)

An efficient synthesis of the title compound 14 is reported, which employs the ZnCl2/Et2O catalyzed addition of acetyl chloride (4) to 2-methyl-2-butene (5) and the ++2> cycloaddition of the 1,1,2,3-tetramethylallyl cation to 2,3-dimethyl-2-butene as key steps.
