Check Digit Verification of cas no

The CAS Registry Mumber 1631033-64-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,1,0,3 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1631033-64:
(9*1)+(8*6)+(7*3)+(6*1)+(5*0)+(4*3)+(3*3)+(2*6)+(1*4)=121
121 % 10 = 1
So 1631033-64-1 is a valid CAS Registry Number.

Gold-catalyzed 5-endo-dig cyclization of 2-[(2-aminophenyl)ethynyl] phenylamine with ketones for the synthesis of spiroindolone and indolo[3,2-c]quinolone scaffolds

Reddy, Basi. V. Subba,Swain, Manisha,Reddy, S. Madhusudana,Yadav,Sridhar

, p. 3313 - 3318 (2014)

A tandem gold-catalyzed 5-endo-dig/spirocyclization of 2-[(2-aminophenyl) ethynyl]phenylamines with isatins was achieved to produce the corresponding 5′,11′-dihydrospiro[indoline-3,6′-indolo[3,2-c]quinolin] -2-one derivatives in good yields with high regioselectivity. This reaction proceeded well at ambient temperature under mild conditions. Ketones also participated smoothly under similar conditions to produce 6,6-disubstituted-6, 11-dihydro-5H-indolo[3,2-c]quinolones. Copyright
