Check Digit Verification of cas no

The CAS Registry Mumber 120255-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,5 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 120255-22:
(8*1)+(7*2)+(6*0)+(5*2)+(4*5)+(3*5)+(2*2)+(1*2)=73
73 % 10 = 3
So 120255-22-3 is a valid CAS Registry Number.

SYNTHESIS OF CYCLOPENTANONES VIA REACTION OF FURAN CHROMIUM CARBENE COMPLEXES WITH ALKYNES

Yamashita, A.,Toy, A.,Watt, W.,Muchmore, C. R.

, p. 3403 - 3406 (1988)

Reactions of the furan-methoxy chromium carbene complexes with alkynes in DMF at 120 deg C provided cyclopentafurans, which served as useful precursors for cyclopentanones and other ring systems.
