Check Digit Verification of cas no

The CAS Registry Mumber 352663-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,2,6,6 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 352663-32:
(8*3)+(7*5)+(6*2)+(5*6)+(4*6)+(3*3)+(2*3)+(1*2)=142
142 % 10 = 2
So 352663-32-2 is a valid CAS Registry Number.

Versatile three-component synthesis of 2'-amino-1,2-dihydrospiro[(3H)- indole-3,4'-(4'H)-pyran]-2-ones

Mortikov,Litvinov,Shestopalov,Rodinovskaya,Shestopalov

experimental part, p. 2373 - 2380 (2010/02/16)

A versatile method for the synthesis of 2'-amino-1,2-dihydrospiro[(3H)- indole-3,4'-(4'H)-pyran]-2-ones has been suggested consisting in the three-component reaction of isatins, cyanoacetic acid derivatives, and α-methylenecarbonyl compounds (β-dicarbonyl compounds, activated phenols, and OH-substituted heterocycles) in ethanol in the presence of triethylamine as a catalyst. The reaction proceeds selectively to form spiro[(3H)-indole-3,4'-(4'H)-pyrans].
