Check Digit Verification of cas no

The CAS Registry Mumber 23180-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,8 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 23180-27:
(7*2)+(6*3)+(5*1)+(4*8)+(3*0)+(2*2)+(1*7)=80
80 % 10 = 0
So 23180-27-0 is a valid CAS Registry Number.

Preparation of chiral 1-benzyl-1,2,3,4-tetrahydroisoquinolines by optical resolution

-

, (2008/06/13)

In a short total synthesis of morphinan compounds, derivatives of 1-benzyl-1,2,3,4-tetrahydroisoquinoline are produced. Certain of these compounds, although highly aromatic and functionalized, can be optically resolved. The optically active enantiomers can serve as important intermediates for both natural and unnatural opioids.
