Check Digit Verification of cas no

The CAS Registry Mumber 857574-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,5,7 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 857574-72:
(8*8)+(7*5)+(6*7)+(5*5)+(4*7)+(3*4)+(2*7)+(1*2)=222
222 % 10 = 2
So 857574-72-2 is a valid CAS Registry Number.

Tandem-type Pd(ii)-catalyzed oxidative Heck reaction/intramolecular C-H amidation sequence: A novel route to 4-aryl-2-quinolinones

supporting information; experimental part, p. 4332 - 4334 (2012/05/20)

A novel catalytic method for synthesizing 4-aryl-2-quinolinones is reported. The process involves two mechanistically independent, sequential Pd(ii)-catalyzed reactions - the oxidative Heck reaction and the intramolecular C-H amidation - both of which smoothly proceed in the presence of a single catalytic system in a one-pot manner.
