Check Digit Verification of cas no

The CAS Registry Mumber 131148-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,4 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131148-96:
(8*1)+(7*3)+(6*1)+(5*1)+(4*4)+(3*8)+(2*9)+(1*6)=104
104 % 10 = 4
So 131148-96-4 is a valid CAS Registry Number.

Stereoselective synthesis of α,γ-diamino-β-hydroxy amino acid esters: A new class of amino acids

Reetz,Wunsch,Harms

, p. 371 - 374 (1990)

Isocyano-acetic acid ethylester 3 undergoes a base catalyzed aldol-type addition to N,N-dibenzylamino aldehydes 6 to form oxazolines 7 stereoselectively; these can be ring-opened with NEt3, affording α,γ-diamino-β-hydroxy amino acid esters 2.
