Check Digit Verification of cas no
The CAS Registry Mumber 22490-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22490-21:
(7*2)+(6*2)+(5*4)+(4*9)+(3*0)+(2*2)+(1*1)=87
87 % 10 = 7
So 22490-21-7 is a valid CAS Registry Number.

A practical synthesis of 2,4-dichloro-3-methyl-6-nitrophenol
Ran,Pittman Jr.
, p. 2785 - 2795 (2007/10/02)
2,4-Dichloro-3-methyl-6-nitrophenol 2 was prepared by KOH/H2O hydrolysis of a product mixture obtained from chlorination of p-nitrotoluene in the presence of a phase transfer catalyst. A 95-99% yield of 2 based on 2,3,6-trichloro-4-nitrotoluene, 4 (major chlorination product) was achieved in >95% purity.
