Check Digit Verification of cas no

The CAS Registry Mumber 1220532-00-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,5,3 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1220532-00:
(9*1)+(8*2)+(7*2)+(6*0)+(5*5)+(4*3)+(3*2)+(2*0)+(1*0)=82
82 % 10 = 2
So 1220532-00-2 is a valid CAS Registry Number.

An expedient synthesis of poly-substituted 1-arylisoquinolines from δ-ketonitriles via indium-mediated Barbier reaction protocol

Kim, Sung Hwan,Lee, Hyun Seung,Kim, Ko Hoon,Kim, Jae Nyoung

experimental part, p. 6476 - 6479 (2011/02/23)

We developed an efficient synthetic strategy of poly-substituted 1-arylisoquinolines via an indium-mediated Barbier type allylation from δ-ketonitriles. Initial attack of allylindium species occurred at the nitrile group selectively to form the enamine intermediate, which reacted with the ketone group intramolecularly to furnish the isoquinolines.
