Check Digit Verification of cas no

The CAS Registry Mumber 20984-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,8 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20984-22:
(7*2)+(6*0)+(5*9)+(4*8)+(3*4)+(2*2)+(1*2)=109
109 % 10 = 9
So 20984-22-9 is a valid CAS Registry Number.

Study toward the synthesis of selenofurans via seleno-Claisen rearrangement of allyl arylselenides

Stefani, Helio A.,Petragnani, Nicola,Ascenso, Maria F. C.,Zeni, Gilson

, p. 2161 - 2166 (2007/10/03)

Selenofuran derivatives were prepared using several phenyl alkenyl selenides via seleno-Claisen rearrangement.

A convenient one-pot preparation of benzo[b] -tellurophenes, - selenophenes, and -thiophenes from o- bromoethynylben zenes

Sashida, Haruki,Sadamori, Kunio,Tsuchiya, Takashi

, p. 713 - 727 (2007/10/03)

2-Substituted and unsubstituted benzo[b]tellurophenes (3Aa-e) were synthesized in one-pot from o-bromoethynylbenzenes (2) via three steps in good yields. Similarly, benzo[b]-selenophenes (3Ba-e) and -thiophenes (3Ca- e) were also obtained.
