Check Digit Verification of cas no

The CAS Registry Mumber 1186219-42-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,2,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1186219-42:
(9*1)+(8*1)+(7*8)+(6*6)+(5*2)+(4*1)+(3*9)+(2*4)+(1*2)=160
160 % 10 = 0
So 1186219-42-0 is a valid CAS Registry Number.

Palladium(II)-catalyzed oxidative carbocyclization of aza-enallenes

Persson, Andreas K. A.,Baeckvall, Jan-E.

supporting information; experimental part, p. 4624 - 4627 (2010/08/19)

(Chemical equation presented) Live and let diene: A palladium(II)-catalyzed oxidative carbocyclization reaction of aza-enallenes provides access to potentially valuable heterocyclic dienes. In the presence of a dieneophile during the carbocyclization step, the products can react further in a one-pot cyclization/ Diels-Alder sequence to give polycyclic products. BQ = para-benzoquinone.
