Check Digit Verification of cas no

The CAS Registry Mumber 864435-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,4,4,3 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 864435-94:
(8*8)+(7*6)+(6*4)+(5*4)+(4*3)+(3*5)+(2*9)+(1*4)=199
199 % 10 = 9
So 864435-94-9 is a valid CAS Registry Number.

Synthesis and properties of 2-(2-furyl)benzothiazole

Melnikova,Elchaninov,Milov,Lukyanov

, p. 1070 - 1076 (2008)

The electrophilic reactions (nitration, bromination, hydroxymethylation, formylation, acylation) and radical substitution reactions (nitration, arylation) of 2-(2-furyl)benzothiazole have been studied. It was found that all of the reactions occur at position 5 of the furan ring. Only nitration in PPA gave the 5′,6-dinitro derivative. Quantum-chemical calculation data for the electron density distribution in the neutral and protonated 2-(2-furyl)benzothiazole molecules are given.
