Check Digit Verification of cas no

The CAS Registry Mumber 1257213-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,1 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1257213-07:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*1)+(3*3)+(2*0)+(1*7)=132
132 % 10 = 2
So 1257213-07-2 is a valid CAS Registry Number.

Asymmetric synthesis of synthetic alkaloids by a tandem biocatalysis/Ugi/Pictet-Spengler-type cyclization sequence

Znabet, Anass,Zonneveld, Job,Janssen, Elwin,De Kanter, Frans J. J.,Helliwell, Madeleine,Turner, Nicholas J.,Ruijter, Eelco,Orru, Romano V. A.

supporting information; experimental part, p. 7706 - 7708 (2010/11/18)

We have combined the biocatalytic desymmetrization of 3,4-cis-substituted meso-pyrrolidines with an Ugi-type multicomponent reaction followed in situ by a Pictet-Spengler-type cyclization reaction sequence for the rapid asymmetric synthesis of alkaloid-like polycyclic compounds.
