Check Digit Verification of cas no

The CAS Registry Mumber 65540-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,4 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65540-54:
(7*6)+(6*5)+(5*5)+(4*4)+(3*0)+(2*5)+(1*4)=127
127 % 10 = 7
So 65540-54-7 is a valid CAS Registry Number.

SYNTHESIS OF ETHYL 3,3-DIALKYL-3'-ALKYLSPIRO-2-CARBOXYLATES

Galin, F. Z.,Ignatyuk, V. K.,Lakeev, S. N.,Rakhimov, R. G.,Sultanova, V. S.,Tolstikov, G. A.

, p. 92 - 98 (2007/10/02)

The alkylation of indene with ultrasonic activation gave quantitative yields of 3-alkylindenes.When heated with ketones in the presence of bases, the latter gave benzofulvenes capable of entering into reaction with ethyl(dimethylsulfuranylidene)acetate with the formation of spirocyclopropane structures.A series of benzofulvenes and the corresponding ethyl 3,3-dialkyl-3'-alkylspiro-2-carboxylates were obtained.
