Check Digit Verification of cas no

The CAS Registry Mumber 1428931-89-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,9,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1428931-89:
(9*1)+(8*4)+(7*2)+(6*8)+(5*9)+(4*3)+(3*1)+(2*8)+(1*9)=188
188 % 10 = 8
So 1428931-89-8 is a valid CAS Registry Number.

α-Palladation of imines as entry to dehydrogenative heck reaction: Aerobic oxidative cyclization of N-allylimines to pyrroles

Chen, Zhiyuan,Lu, Beili,Ding, Zhenhua,Gao, Ke,Yoshikai, Naohiko

supporting information, p. 1966 - 1969 (2013/06/04)

We report here a palladium(II)-catalyzed oxidative cyclization reaction of N-allylimines derived from methyl ketones, typically acetophenones, affording pyrrole derivatives at room temperature under oxygen atmosphere. The reaction likely proceeds through α-palladation of the imine followed by olefin migratory insertion and β-hydride elimination, thus representing a new example of aerobic dehydrogenative Heck cyclization.
