Check Digit Verification of cas no

The CAS Registry Mumber 627877-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,8,7 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 627877-60:
(8*6)+(7*2)+(6*7)+(5*8)+(4*7)+(3*7)+(2*6)+(1*0)=205
205 % 10 = 5
So 627877-60-5 is a valid CAS Registry Number.

Development of Chiral Nucleophilic Pyridine Catalysts: Applications in Asymmetric Quaternary Carbon Synthesis

Shaw, Scott A.,Aleman, Pedro,Vedejs, Edwin

, p. 13368 - 13369 (2007/10/03)

TADMAP (1a), a new chiral DMAP catalyst, has been designed to place a C(3)-benzylic trityl group over one face of the pyridine ring, while a C(3)-benzylic acetoxy group creates a chirotopic environment on the other face. TADMAP was prepared in four steps
