Check Digit Verification of cas no

The CAS Registry Mumber 134880-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,8 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134880-12:
(8*1)+(7*3)+(6*4)+(5*8)+(4*8)+(3*0)+(2*1)+(1*2)=129
129 % 10 = 9
So 134880-12-9 is a valid CAS Registry Number.

Asymmetric syntheses of 3-substituted-cyclohexanone derivatives by stereoselective conjugate addition to chiral 2-substituted-2-cyclohexen-1-ones

Schultz, Arthur G.,Harrington, Roger E.

, p. 4926 - 4931 (2007/10/02)

Chiral 2-substituted-2-cyclohexen-1-one 2a is prepared from 1a by Birch reduction followed by acid-catalyzed hydrolysis-olefin migration. Conjugate additions of organometallic reagents to 2a occur with good to excellent diastereoselectivities (Table I). E
