Check Digit Verification of cas no

The CAS Registry Mumber 1147090-61-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,0,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1147090-61:
(9*1)+(8*1)+(7*4)+(6*7)+(5*0)+(4*9)+(3*0)+(2*6)+(1*1)=136
136 % 10 = 6
So 1147090-61-6 is a valid CAS Registry Number.

Direct syntheses of 4-aryl-1,2,3,4-tetrahydroisoquinolines and 1-aryl-2,3,4,5-tetrahydro-3-benzoazepines via hydroamination of enol carbamates

Crecente-Campo, José,Vázquez-Tato, M. Pilar,Seijas, Julio A.

experimental part, p. 2655 - 2659 (2009/06/20)

An efficient and simple procedure for the syntheses of 4-aryl-1,2,3,4-tetrahydroisoquinolines and 1-aryl-2,3,4,5-tetrahydro-3-benzoazepines has been developed. The approach uses easily available starting materials and requires just three steps. The hydroamination of an enol carbamate is the key step. This general and direct method has been applied to the total synthesis of the natural alkaloid cherylline and to biologically active 3-benzoazepines as well.
