Check Digit Verification of cas no

The CAS Registry Mumber 566949-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,6,9,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 566949-99:
(8*5)+(7*6)+(6*6)+(5*9)+(4*4)+(3*9)+(2*9)+(1*9)=233
233 % 10 = 3
So 566949-99-3 is a valid CAS Registry Number.

Asymmetric synthesis of allyl- and α-allenylamines from chiral imines and alkynes via (η2-imine)Ti(O-i-Pr)2 complexes

Fukuhara, Kohki,Okamoto, Sentaro,Sato, Fumie

, p. 2145 - 2148 (2003)

(Matrix presented) The reaction of a divalent titanium reagent Ti(O-i-Pr)4/2i-PrMgX with optically active arylaldimines derived from arylaldehydes and O-methylphenylglycinol provided, in a highly diastereoselective manner, chiral (η2-imine)Ti(O-i-Pr) 2 complexes, which in turn reacted with 1-alkynes or propargyl compounds to give optically active allyl- and α-allenylamines, respectively.
