99142-37-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99142-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99142-37:
(7*9)+(6*9)+(5*1)+(4*4)+(3*2)+(2*3)+(1*7)=157
157 % 10 = 7
So 99142-37-7 is a valid CAS Registry Number.

Bifunctionalization of α,ω-Sulphonamides via Kinetically Controlled Reaction of α,ω-Bis(N-nitrososulphonamides)
Iwata, Masaaki,Kuzuhara, Hiroyoshi
, p. 918 - 919 (2007/10/02)
α,ω-Bis(N-nitrososulphonamides) in hot benzene were converted into α,ω-disulphonates and bifunctional α-sulphonate-ω-sulphonamides, in good yields, by intramolecular N-nitrososulphonamide-sulphonate rearrangement.
