Check Digit Verification of cas no
The CAS Registry Mumber 138832-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,3 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138832-38:
(8*1)+(7*3)+(6*8)+(5*8)+(4*3)+(3*2)+(2*3)+(1*8)=149
149 % 10 = 9
So 138832-38-9 is a valid CAS Registry Number.

An improved method for the preparation of β-substituted cyclohexenones is reported. Conditions were defined to effectuate the key desulfonylation-deketalization step in a mild manner. Several cyclohexenones bearing acid and/or base sensitive β-substituents were prepared by the modified method in moderate to good yields.
