Check Digit Verification of cas no

The CAS Registry Mumber 90338-06-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,3 and 8 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90338-06:
(7*9)+(6*0)+(5*3)+(4*3)+(3*8)+(2*0)+(1*6)=120
120 % 10 = 0
So 90338-06-0 is a valid CAS Registry Number.

TRIFLUOROACETYLATION OF 3-HALO-9-METHYLCARBAZOLES

Moskalev, N. V.,Sirotkina, E. E.

, p. 1192 - 1195 (2007/10/02)

Trifluoroacetylation of 3-halo-9-methylcarbazoles at 110 deg C proceeds at 6-position.In the case of 3-bromo- and 3-iodo-derivatives, the reaction is complicated by competing processes of dehalogenation, followed by the halogenation of the substrate, leading to 3,6-dihalo derivatives.
