Check Digit Verification of cas no

The CAS Registry Mumber 138736-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138736-91:
(8*1)+(7*3)+(6*8)+(5*7)+(4*3)+(3*6)+(2*9)+(1*1)=161
161 % 10 = 1
So 138736-91-1 is a valid CAS Registry Number.

Synthesis of a new chiral bisphosphine ligand, MOCBP, and its use in rhodium(I)-catalyzed asymmetric hydrogenation of a cyclic enamide

Morimoto,Nakajima,Achiwa

, p. 75 - 78 (1995)

A new chiral bisphosphine ligand (6) bearing a cyclobutane framework was readily prepared by using diastereoselective [2 + 2] cycloaddition. Its rhodium(I) complex was found to be an efficient catalyst for the asymmetric hydrogenation of a cyclic enamide, N-acetyl-1-methylene-1,2,3,4-tetrahydroisoquinoline (9), affording (R)-(-)-N-acetylsalsolidine (10) in up to 80.6% ee.

A practical asymmetric synthesis of the antiviral agent lobucavir, BMS-180194

, p. 393 - 399 (2013/09/08)

A practical synthesis of the antiviral agent lobucavir, [1R-(1α,2β,3α)]-2-amino-9-[2,3-bis(hydroxymethyl)cyclobutyl]- 6H-purin-6-one (BMS-180194), is described. The key chiral intermediate, [1S-(1α,2β,3α)]-3-hydroxy-1,2-cyclobutanedimethanol, dibenzoate e
