Check Digit Verification of cas no

The CAS Registry Mumber 1233239-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,2,3 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1233239-33:
(9*1)+(8*2)+(7*3)+(6*3)+(5*2)+(4*3)+(3*9)+(2*3)+(1*3)=122
122 % 10 = 2
So 1233239-33-2 is a valid CAS Registry Number.

The NHCs-mediated cross-coupling of aromatic aldehydes with benzyl halides: Synthesis of α-aryl ketones

Lin, Lu,Li, Yi,Du, Wenting,Deng, Wei-Ping

scheme or table, p. 3571 - 3574 (2010/08/07)

A new NHCs-mediated synthetic method was found to produce α-aryl ketones in 22-63% yields in one-pot process from the corresponding aromatic aldehydes and benzyl halides. This method is the first example of the NHCs-mediated intermolecular nucleophilic acylation of aromatic aldehydes with benzyl halides.
