199449-96-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199449-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,4 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 199449-96:
(8*1)+(7*9)+(6*9)+(5*4)+(4*4)+(3*9)+(2*9)+(1*6)=212
212 % 10 = 2
So 199449-96-2 is a valid CAS Registry Number.

Dibenz[a,c]anthracene: Electrophilic substitution and synthesis of phenol isomers
Harvey, Ronald G.,Aboshkara, Elias,Pataki, John
, p. 15947 - 15956 (2007/10/03)
Efficient syntheses of the 3-, 9-, 10-, and 11-phenol isomers of dibenz[a,c]anthracene [DBa,cA) and 2,3-dihydroxy-DBa,cA are described. Bromination of DBa,cA with bromine in CH2Cl2 gave 10-bromo-DBa,cA and not 9-bromo-DBa,cA predicte
