Check Digit Verification of cas no

The CAS Registry Mumber 597581-23-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,7,5,8 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 597581-23:
(8*5)+(7*9)+(6*7)+(5*5)+(4*8)+(3*1)+(2*2)+(1*3)=212
212 % 10 = 2
So 597581-23-2 is a valid CAS Registry Number.

Benzylsulfonyl: A valuable protecting and deactivating group in phenol chemistry

Briot, Anne,Baehr, Corinne,Brouillard, Raymond,Wagner, Alain,Mioskowski, Charles

, p. 965 - 967 (2003)

We introduce benzylsulfonyl (Bns) as a valuable protecting group in phenol chemistry. Bns proved to be stable under drastic reaction conditions and towards many common reagents. The deprotection proceeds quantitatively using catalytic hydrogenolysis. Additionally the Bns deactivating properties make this protecting group useful for tuning the reactivity of phenolic substrates.
