1111249-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1111249-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,2,4 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1111249-52:
(9*1)+(8*1)+(7*1)+(6*1)+(5*2)+(4*4)+(3*9)+(2*5)+(1*2)=95
95 % 10 = 5
So 1111249-52-5 is a valid CAS Registry Number.

Instantaneous deprotection of tosylamides and esters with Sml 2/amine/water
Ankner, Tobias,Hilmersson, Goeran
supporting information; experimental part, p. 503 - 506 (2009/07/11)
(Chemical Equation Presented) Sml2/amine/water mediates instantaneous cleavage of tosyl amides and tosyl esters. Highly hindered, sensitive and functionalized substrates were successfully deprotected in near quantitative yield.
