Check Digit Verification of cas no

The CAS Registry Mumber 585509-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,5,5,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 585509-89:
(8*5)+(7*8)+(6*5)+(5*5)+(4*0)+(3*9)+(2*8)+(1*9)=203
203 % 10 = 3
So 585509-89-3 is a valid CAS Registry Number.

The desymmetrisation of resorcinol: The synthesis of resorcinol monoalkyl ethers

Boxhall, Jonathan Y.,Page, Philip C. Bulman,Chan, Yohan,Hayman, Colin M.,Heaney, Harry,McGrath, Matthew J.

, p. 997 - 1001 (2007/10/03)

The desymmetrisation of resorcinol to give 3-alkoxyresorcinol derivatives can be achieved in excellent yields either from resorcinol monobenzoate and alcohols using Mitsunobu reactions followed by hydrolysis using a strong base or by using 3-iodophenylbenzyl ether as a resorcinol monobenzyl ether equivalent in reactions with alcohols catalysed by copper(I)-9,10-phenanthroline followed by ammonium formate-palladium catalysed hydrogenolysis.
