Check Digit Verification of cas no

The CAS Registry Mumber 108774-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,7,7 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108774-52:
(8*1)+(7*0)+(6*8)+(5*7)+(4*7)+(3*4)+(2*5)+(1*2)=143
143 % 10 = 3
So 108774-52-3 is a valid CAS Registry Number.

Heck reaction: Stereo selective synthesis of trisubstituted olefins: Useful intermediates for anthraquinone carboxylic acid derivatives

Rama Devi,Rajaram

, p. 591 - 597 (2007/10/03)

Palladium catalyzed arylation of dialkyl itaconate in presence of Pd(OAc)2/PPh3 as a catalyst, afforded trisubstituted olefins stereo selectively. These alkenes are useful intermediates for the synthesis of anthraquinone carboxylic acid derivatives. A new coumarin is also synthesized using this protocol.
