Check Digit Verification of cas no
The CAS Registry Mumber 77202-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77202-76:
(7*7)+(6*7)+(5*2)+(4*0)+(3*2)+(2*7)+(1*6)=127
127 % 10 = 7

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.
