71452-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71452-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,5 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71452-19:
(7*7)+(6*1)+(5*4)+(4*5)+(3*2)+(2*1)+(1*9)=112
112 % 10 = 2
So 71452-19-2 is a valid CAS Registry Number.

The Simpliest Biformazan: 1,1',5,5'-Tetraphenyl-3,3'-biformazan
Neugebauer, Franz Alfred,Fischer, Hans
, p. 1226 - 1234 (2007/10/02)
The synthesis and the properties of the biformazan 9 are reported.Dehydrogenation of 9 yields the betain 20, which like the salt 21 represents the middle oxidation state between the biformazan 9 and the bis(tetrazolium salt) 22.
