Check Digit Verification of cas no

The CAS Registry Mumber 1263210-10-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,2,1 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1263210-10:
(9*1)+(8*2)+(7*6)+(6*3)+(5*2)+(4*1)+(3*0)+(2*1)+(1*0)=101
101 % 10 = 1
So 1263210-10-1 is a valid CAS Registry Number.

Formal synthesis of the bisbenzylisoquinoline alkaloid berbamunine by asymmetric substitution of chiral organolithium compounds

Gawley, Robert E.,Smith, Gregory A.

, p. 167 - 179 (2011/07/07)

Asymmetric alkylation of enantiomeric tetrahydroisoquinolyl oxazolines was achieved with 96-97% diastereoselectivity. Removal of the oxazoline chiral auxiliary and further transformations provide a straightforward synthesis of the two synthetic intermediates that were previously synthesized by resolution, and which comprise a formal synthesis of berbamunine by Ullman coupling.
