Check Digit Verification of cas no

The CAS Registry Mumber 1312929-67-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,2 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1312929-67:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*2)+(3*9)+(2*6)+(1*7)=151
151 % 10 = 1
So 1312929-67-1 is a valid CAS Registry Number.

Enantiocontrolled synthesis of β-branched α-amino acids by using CuI-catalyzed 1,4-addition of glycine imines to β-substituted gem-diactivated olefins

Hernandez-Toribio, Jorge,Arrayas, Ramon Gomez,Carretero, Juan C.

supporting information; experimental part, p. 6334 - 6337 (2011/08/06)

Branching out! The catalytic asymmetric conjugate addition of glycinate Schiff bases to β-substituted gem-diactivated Michael acceptors under proton transfer conditions gives a variety of β-branched α-amino acids (see scheme; Dpm=diphenylmethylene, EWG=electron-withdrawing group) with excellent levels of diastereo- (typically syn/anti >90:10) and enantiocontrol (90-99 % ee).
