Check Digit Verification of cas no
The CAS Registry Mumber 21120-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21120-91:
(7*2)+(6*1)+(5*1)+(4*2)+(3*0)+(2*9)+(1*1)=52
52 % 10 = 2
So 21120-91-2 is a valid CAS Registry Number.

Synthesis and Rearrangements of 1,1'-Bi(benzocyclobutylidene) and its Derivatives
Barton, John W.,Shepherd, Michael K.
, p. 1561 - 1566 (2007/10/02)
Convenient new preparations of 1-halogeno-1,2-dihydrobenzocyclobutenes (5) and (6) and 1,1'-bi(benzocyclobutylidene) (4) are described.The hydrocarbon (4) is susceptible to cationic rearrangements: it forms 5,10-dihydroindenoindene (16) on protonation in acetic anhydride, and is oxidised by selenium(IV) oxide to a mixture of the spiroketone (17) and 5H-indeno-benzopyran-2-one (18).The mechanisms of these and other rearrangements are discussed.
