66012-73-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66012-73-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,1 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66012-73:
(7*6)+(6*6)+(5*0)+(4*1)+(3*2)+(2*7)+(1*3)=105
105 % 10 = 5
So 66012-73-5 is a valid CAS Registry Number.

1,1′-Diaryl-5,5′-bitetrazoles, unlike 1,1′-dimethyl derivative, are Hammett bases which are much weaker than their monocyclic analogs. Bitetrazoles undergo monoprotonation in the H0 range from -5 to -9, and their pKBH+ values correla
