146849-08-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146849-08-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,8,4 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 146849-08:
(8*1)+(7*4)+(6*6)+(5*8)+(4*4)+(3*9)+(2*0)+(1*8)=163
163 % 10 = 3
So 146849-08-3 is a valid CAS Registry Number.

Synthesis of ortho-alkylated 4,4'-diaminodiphenylmethanes
Chiang,Mei
, p. 7869 - 7872 (2007/10/02)
Procedures are described to convert 4,4'-diaminodiphenylmethane into its ortho-(methylthiomethyl) derivatives. Mechanism for formation of ortho-dialkylated products is discussed and generalizations for dialkylation are founded.
