1257108-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1257108-01-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,1,0 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1257108-01:
(9*1)+(8*2)+(7*5)+(6*7)+(5*1)+(4*0)+(3*8)+(2*0)+(1*1)=132
132 % 10 = 2
So 1257108-01-2 is a valid CAS Registry Number.

Synthetic approaches to bicyclic diazenium salts
Wyman,Javed,Al-Bataineh,Brewer
, p. 8078 - 8087 (2011/03/22)
Bicyclic diazenium salts have been prepared from α-chloroazo species via a Lewis acid-mediated intramolecular cycloaddition. An alternative, more direct, route to these salts by the reaction of hydrazones with dimethylsulfonium ditriflate is also describe
