Check Digit Verification of cas no

The CAS Registry Mumber 3232-12-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,3 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3232-12:
(6*3)+(5*2)+(4*3)+(3*2)+(2*1)+(1*2)=50
50 % 10 = 0
So 3232-12-0 is a valid CAS Registry Number.

Tributylphosphine, excellent organocatalyst for conjugate additions of non-nucleophilic N-containing compounds

Gimbert, Carolina,Moreno-Ma?as, Marcial,Pérez, Elisabet,Vallribera, Adelina

, p. 8305 - 8310 (2008/02/05)

Conjugate additions of non-nucleophilic N-containing compounds such as amides, thioamides, sulfonamides, and electron-poor anilines with different Michael acceptors can be promoted through the use of tributylphosphine. The range of useful pKa's of nucleophiles has been established (pKa25) and new insights into the mechanism proposed.
