Check Digit Verification of cas no

The CAS Registry Mumber 1428319-22-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1428319-22:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*1)+(3*9)+(2*2)+(1*2)=155
155 % 10 = 5
So 1428319-22-5 is a valid CAS Registry Number.

Salen promoted enantioselective nazarov cyclizations of activated and unactivated dienones

Hutson, Gerri E.,Tuerkmen, Yunus E.,Rawal, Viresh H.

supporting information, p. 4988 - 4991 (2013/05/21)

A novel class of chiral 5,5′-di(2,4,6-trialkyl)aryl salen-metal complexes have been developed and shown to catalyze highly enantioselective Nazarov cyclization reactions, giving rise to cyclopentenoids in 90:10-98:2 er. Significantly, the catalysts also p
