Check Digit Verification of cas no
The CAS Registry Mumber 678194-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,8,1,9 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 678194-47:
(8*6)+(7*7)+(6*8)+(5*1)+(4*9)+(3*4)+(2*4)+(1*7)=213
213 % 10 = 3
So 678194-47-3 is a valid CAS Registry Number.

Nucleophile-selective selenocyclizations
Khokhar, Shaista S.,Wirth, Thomas
, p. 4567 - 4581 (2007/10/03)
Electrophilic cyclizations are one of the major strategies for cyclofunctionalizations of alkenes. Selective selenocyclizations can be performed by adjusting various factors in such reactions. The nature of the electrophile, the counterion, solvents, and
