137654-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137654-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137654-42:
(8*1)+(7*3)+(6*7)+(5*6)+(4*5)+(3*4)+(2*4)+(1*2)=143
143 % 10 = 3
So 137654-42-3 is a valid CAS Registry Number.

, p. 7447 - 7458 (2007/10/02)
Cesium fluoroxysulfate was proved to be a N-fluorinating agent for some nitrogen compounds. Yields of products obtained, mainly monofluoro-derivatives, depend on structures of initial nitrogen compounds. The ability of cesium fluoroxysylfate for N-fluorin
