Check Digit Verification of cas no

The CAS Registry Mumber 222416-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,4,1 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 222416-33:
(8*2)+(7*2)+(6*2)+(5*4)+(4*1)+(3*6)+(2*3)+(1*3)=93
93 % 10 = 3
So 222416-33-3 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.
