1280224-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1280224-70-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,2 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1280224-70:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*2)+(3*4)+(2*7)+(1*0)=125
125 % 10 = 5
So 1280224-70-5 is a valid CAS Registry Number.

PdCl2-catalyzed hydrosulfonamidation of homo allylic alcohols: An efficient synthesis of allylic sulfonamides
Sreedhar,Ravi,Yada, Deepthi
, p. 1208 - 1212 (2011)
A new protocol for the palladium chloride-catalyzed direct hydrosulfonamidation of homoallylic alcohols with migration of the double bond is described. This method requires no preactivation of alcohols and the reaction is environmentally benign with water
