Check Digit Verification of cas no

The CAS Registry Mumber 1280289-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1280289-44:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*8)+(3*9)+(2*4)+(1*4)=162
162 % 10 = 2
So 1280289-44-2 is a valid CAS Registry Number.

Pd-Catalyzed borylative polycyclization of enediynes to alkylboronates

Marco-Martinez, Juan,Bunuel, Elena,Lopez-Duran, Ruth,Cardenas, Diego J.

, p. 2734 - 2741 (2011)

Pd-catalyzed bicyclization of 1-ene-6,11-diynes with bis(pinacolato)diboron smoothly affords synthetically useful homoallylic alkylboronates under mild conditions, avoiding the use of highly nucleophilic or basic reagents. One Ci￡B bond and two new Ci￡C b
