Check Digit Verification of cas no

The CAS Registry Mumber 1250832-26-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,8,3 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1250832-26:
(9*1)+(8*2)+(7*5)+(6*0)+(5*8)+(4*3)+(3*2)+(2*2)+(1*6)=128
128 % 10 = 8
So 1250832-26-8 is a valid CAS Registry Number.

Synthesis and Suzuki-Miyaura reactions of 5-halo-3,4-dihydropyrimidin-2(1H) -ones

Zych, Andrew J.,Wang, Hong-Jun,Sakwa, Samuel A.

experimental part, p. 5103 - 5105 (2010/11/16)

A novel synthesis of 6-methyl-4-phenyl-5-substituted-3,4-dihydropyrimidin- 2(1H)-ones from 6-methyl-4-phenyl-5-halo-3,4-dihydropyrimidin-2(1H)-ones via the Suzuki-Miyaura reaction is reported. These previously unknown heterocyclic halides are easily prepared using the Biginelli multicomponent reaction followed by halodecarboxylation. The effect of varied substitution at the C-4 position on the cross-coupling reaction is also examined.
