Check Digit Verification of cas no

The CAS Registry Mumber 1428188-07-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,1,8 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1428188-07:
(9*1)+(8*4)+(7*2)+(6*8)+(5*1)+(4*8)+(3*8)+(2*0)+(1*7)=171
171 % 10 = 1
So 1428188-07-1 is a valid CAS Registry Number.

One-pot, three-component synthesis of novel 4-phenyl-2-[3-(alkynyl/alkenyl/ aryl)phenyl]pyrimidine libraries via michael addition, cyclization, and C-C coupling reactions: A new MCR strategy

Reddy, L.Srinivasula,Reddy, T.Ram,Reddy, N.C. Gangi,Mohan, Reddybodireddy,Lingappa

, p. 75 - 84 (2013)

Privileged medicinal scaffolds based on the structures of 4-phenyl-2-[3-(alkynyl/alkenyl/aryl)phenyl]-substituted pyrimidines have been synthesized via a single-step, three-component reaction of 3-(dimethylamino)-1- phenylprop-2-en-1-one (enaminone), 3-bromobenzimidamide hydrochloride, and various alkynes/alkenes/arylboronic acids. The mechanism of this multi-component reaction (MCR) involves a Michael addition, cyclization, isomerization, and dehydration, followed by Sonogashira, Heck or Suzuki coupling. This new MCR strategy afforded a new compound library based on pyrimidine framework. Georg Thieme Verlag Stuttgart · New York.
