Check Digit Verification of cas no

The CAS Registry Mumber 3648-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3648-76:
(6*3)+(5*6)+(4*4)+(3*8)+(2*7)+(1*6)=108
108 % 10 = 8
So 3648-76-8 is a valid CAS Registry Number.

Synthesis of spiro[isoquinoline-4,4′-pyran]-3-imines

Kisel',Platonov,Kostyrko,Kovtunenko

, p. 905 - 910 (2000)

A method has been developed for the synthesis of 4-[2-(bromomethyl)phenyl]tetrahydro-2H-4-pyrancarbonitrile and a study was carried out on the reaction of this compound with primary amines, which, depending on the conditions, leads to either 4-[2-(R-aminomethyl)phenyl]tetrahydro-2H-4-pyrancarbonitriles or hydrobromides of 2-R- aryl-2,3,2′,3′,5′,6′-hexahydrospiro[isoquinoline- 4(1H),4′-pyran]-3-imines.
