Check Digit Verification of cas no

The CAS Registry Mumber 162-70-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,6 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 162-70:
(5*1)+(4*6)+(3*2)+(2*7)+(1*0)=49
49 % 10 = 9
So 162-70-9 is a valid CAS Registry Number.

Structure of the Cornubert ketone

Pettit, George R.,Thomas, Evan G.

, p. 629 - 633 (1982)

The self-condensation of cyclohexanone in diethyl ether catalyzed by sodium amide has been found to provide a one-step route to pyran 3.Evidence is presented that the Cornubert ketone formed by this reaction corresponds to ketol 2 which readily rearranges
