Check Digit Verification of cas no

The CAS Registry Mumber 557089-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,7,0,8 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 557089-72:
(8*5)+(7*5)+(6*7)+(5*0)+(4*8)+(3*9)+(2*7)+(1*2)=192
192 % 10 = 2
So 557089-72-2 is a valid CAS Registry Number.

Enantiopure guanidine bases for enantioselective enone epoxidations: 2, cyclic guanidines

McManus, Julie C.,Genski, Thorsten,Carey, John S.,Taylor, Richard J. K.

, p. 369 - 371 (2003)

A range of structurally and functionally varied enantiopure cyclic and bicyclic guanidines has been prepared and evaluated in the enantioselective epoxidation of 3-tert-butoxycarbonylamino-4,4-dimethoxycyclohexa-2,5-dien-1-one 1 using tert-butylhydroperoxide. Encouraging enantiomeric excesses were observed (up to 60%). Low enantiomeric excesses were also observed with 2-methylnaphthoquinone and trans-chalcone.
