19717-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19717-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,1 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19717-44:
(7*1)+(6*9)+(5*7)+(4*1)+(3*7)+(2*4)+(1*4)=133
133 % 10 = 3
So 19717-44-3 is a valid CAS Registry Number.

The first general synthetic approach to 1,1′-bisindoles is described. Two simultaneous, ambient temperature Mori-Ban reactions were used to effect bisindolization of several diallylated hydrazobenzenes with minimal cleavage of the N-N bond.
