Check Digit Verification of cas no

The CAS Registry Mumber 186757-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,7,5 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 186757-98:
(8*1)+(7*8)+(6*6)+(5*7)+(4*5)+(3*7)+(2*9)+(1*8)=202
202 % 10 = 2
So 186757-98-2 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.
