1431934-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431934-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,9,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1431934-71:
(9*1)+(8*4)+(7*3)+(6*1)+(5*9)+(4*3)+(3*4)+(2*7)+(1*1)=152
152 % 10 = 2
So 1431934-71-2 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.
