Check Digit Verification of cas no
The CAS Registry Mumber 73775-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,7 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73775-59:
(7*7)+(6*3)+(5*7)+(4*7)+(3*5)+(2*5)+(1*9)=164
164 % 10 = 4
So 73775-59-4 is a valid CAS Registry Number.

1-(Phenylethynyl)aziridine in reactions with amines
Tikhomirov,Porchinskaya,Eremeev
, p. 498 - 501 (2007/10/02)
The reaction of 1-(phenylethynyl)aziridine with a primary or secondary amine gave 2-benzylimidazoline-2 or N-aminoethyl substituted phenylacetamidine via nucleophilic attack on the aziridine ring. The mechanism of aziridine ring opening by an amine was studied.
