Check Digit Verification of cas no

The CAS Registry Mumber 1433688-86-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,6,8 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1433688-86:
(9*1)+(8*4)+(7*3)+(6*3)+(5*6)+(4*8)+(3*8)+(2*8)+(1*6)=188
188 % 10 = 8
So 1433688-86-8 is a valid CAS Registry Number.

Consecutive SNH and Suzuki-Miyaura cross-coupling reactions-an efficient synthetic strategy to pyrimidines bearing pyrrole and indole fragments

Verbitskiy, Egor V.,Rusinov, Gennady L.,Charushin, Valery N.,Chupakhin, Oleg N.,Cheprakova, Ekaterina M.,Slepukhin, Pavel A.,Pervova, Marina G.,Ezhikova, Marina A.,Kodess, Mikhail I.

The combination of the Suzuki-Miyaura cross-coupling and nucleophilic aromatic substitution of hydrogen reactions is a versatile tool for the syntheses of 4-(1R-pyrrol-2-yl)-and 4-(1R-indol-3-yl)-5-(hetero)aryl-substituted pyrimidines from commercially available 5-bromopyrimidine. The S NH [AE, (addition-elimination)] and SN H [AO, (addition-oxidation)] reactions of 5-bromopyrimidine with pyrroles and indoles were studied by gas chromatography-mass spectrometry. The structures of the intermediate σH adducts as well as the pyrrole-(hetero)arylpyrimidine and indole-(hetero)arylpyrimidine dyads were established for the first time by X-ray crystal structure analysis.
