Check Digit Verification of cas no

The CAS Registry Mumber 680620-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,6,2 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 680620-56:
(8*6)+(7*8)+(6*0)+(5*6)+(4*2)+(3*0)+(2*5)+(1*6)=158
158 % 10 = 8
So 680620-56-8 is a valid CAS Registry Number.

Asymmetric synthesis of cyclopentenones with benzylic α-quaternary carbon stereogenic centres from furans

Csaky, Aurelio G.,Mba, Myriam,Plumet, Joaquin

, p. 647 - 652 (2007/10/03)

A new procedure for the synthesis of cyclopentenones containing benzylic α-quaternary carbon stereogenic centres is reported. This method makes use of a one-pot alkylation-elimination sequence from readily available starting materials and simple procedures, which makes it useful for the large-scale preparation of densely functionalised cyclopentanoids.
