77222-67-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77222-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,2 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77222-67:
(7*7)+(6*7)+(5*2)+(4*2)+(3*2)+(2*6)+(1*7)=134
134 % 10 = 4
So 77222-67-4 is a valid CAS Registry Number.

Synthesis of 1,1-Diphenylaminoalcohols
Bertram, Juergen
, p. 44 - 51 (2007/10/02)
The synthesis of 2-amino-2-methyl-1,1-diphenyl-1-propanol (2a) and some of its aryl- and N-substituted derivatives from amino acid esters and Grignard compounds is described.The limits of this synthesis are reported, and so are other methods for the synthesis of amino alcohols.
