Check Digit Verification of cas no

The CAS Registry Mumber 1240403-33-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,4,0 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1240403-33:
(9*1)+(8*2)+(7*4)+(6*0)+(5*4)+(4*0)+(3*3)+(2*3)+(1*3)=91
91 % 10 = 1
So 1240403-33-1 is a valid CAS Registry Number.

The double addition reaction of alkoxymethyl nucleophiles to esters to generate novel polyoxygenated species

Verma, Vishal A.,Arasappan, Ashok,Njoroge, F. George

experimental part, p. 4284 - 4286 (2010/09/07)

The development of a double addition reaction of alkoxylmethyl nucleophiles to a variety of functionalized aryl and alkyl esters to give polyoxygenated products is reported. Key features include broad electrophile substrate scope and good yields. Structurally diverse nucleophiles were investigated and were found to successfully undergo diaddition. This development now allows facile access to this novel class of polyoxygenated molecules.
