Check Digit Verification of cas no

The CAS Registry Mumber 893411-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,4,1 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 893411-52:
(8*8)+(7*9)+(6*3)+(5*4)+(4*1)+(3*1)+(2*5)+(1*2)=184
184 % 10 = 4
So 893411-52-4 is a valid CAS Registry Number.

, p. 6287 - 6289 (2015/10/20)

A general synthetic route to spiro[2.5]octane-5,7-dione and spiro[3.5]nonane-6,8-dione that involves cyclization of the related acrylates and diethyl acetonedicarboxylate, followed by decarboxylation, has been developed. Compared with previous synthetic methods, the developed protocol avoids the use of column chromatography in each of the synthetic steps. Therefore, it can be readily scaled-up. The use of diethyl acetonedicarboxylate under mild conditions to build the skeleton of 1,3-cyclohexanedione has proved to be very efficient.
