Check Digit Verification of cas no

The CAS Registry Mumber 1318800-21-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,8,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1318800-21:
(9*1)+(8*3)+(7*1)+(6*8)+(5*8)+(4*0)+(3*0)+(2*2)+(1*1)=133
133 % 10 = 3
So 1318800-21-3 is a valid CAS Registry Number.

Palladium-catalyzed approach to primary amides using nongaseous precursors

Nielsen, Dennis U.,Taaning, Rolf H.,Lindhardt, Anders T.,Gogsig, Thomas M.,Skrydstrup, Troels

, p. 4454 - 4457 (2011)

A simple protocol is reported for the preparation of primary aryl amides under Pd-catalyzed carbonylation chemistry applying a two-chamber system with crystalline and nontransition metal based sources of carbon monoxide and ammonia. The method is suitable for the synthesis of a number of primary amides with good functional group tolerance. Incorporation of 13CO into the primary amide group was also found to be effective making this approach useful for accessing carbon isotope labeled derivatives.
