Check Digit Verification of cas no

The CAS Registry Mumber 548740-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,7,4 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 548740-13:
(8*5)+(7*4)+(6*8)+(5*7)+(4*4)+(3*0)+(2*1)+(1*3)=172
172 % 10 = 2
So 548740-13-2 is a valid CAS Registry Number.

π-deficient 2-(arylsulfonyl)ethyl esters as protecting groups for carboxylic acids

Alonso, Diego A.,Nájera, Carmen,Varea, Montserrat

, p. 277 - 287 (2007/10/03)

Several π-deficient 2-(arylsulfonyl)ethyl groups have been studied as carboxylic acid protecting groups. The 2-[3,5-bis(trifluoromethyl)phenylsulfonyl]ethyl group is the most easily removed protecting group for acids under mild basic conditions using aqueous NaHCO3.
