Check Digit Verification of cas no

The CAS Registry Mumber 321998-14-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,9,9 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 321998-14:
(8*3)+(7*2)+(6*1)+(5*9)+(4*9)+(3*8)+(2*1)+(1*4)=155
155 % 10 = 5
So 321998-14-5 is a valid CAS Registry Number.

A general strategy for the synthesis of difluoromethyl-containing pyrazoles, pyridines and pyrimidines

Iaroshenko, Viktor O.,Specowius, Verena,Vlach, Katharina,Vilches-Herrera, Marcelo,Ostrovskyi, Dmytro,Mkrtchyan, Satenik,Villinger, Alexander,Langer, Peter

experimental part, p. 5663 - 5677 (2011/08/22)

Difluoromethyl-containing heteroannulated pyridines, pyrimidines and pyrazoles are prepared by a two step method. The regioselective cyclizations of electron-excessive aminoheterocycles, hydrazines and amidines with CF 2Cl-substituted 1,3-dicarbonyl compounds provide the corresponding CF2Cl-substituted heterocycles. Subsequent radical reactions with trimethylstannane or allyltrimethylstannane gave difluoromethyl-containing heteroannulated pyridines, pyrimidines and pyrazoles, respectively.
