Check Digit Verification of cas no
The CAS Registry Mumber 1003856-43-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,3,8,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1003856-43:
(9*1)+(8*0)+(7*0)+(6*3)+(5*8)+(4*5)+(3*6)+(2*4)+(1*3)=116
116 % 10 = 6
So 1003856-43-6 is a valid CAS Registry Number.

Palladium-catalyzed Suzuki-Miyaura coupling of N-benzenesulfonyl-3,4-dibromopyrrole with a variety of arylboronic acids gave the corresponding 3,4-diarylpyrroles in high yields. The 3,4-differentially arylated pyrroles could also be prepared by stepwise cross-coupling approach. The total syntheses of lamellarins O, P, Q, and R have been achieved by using the cross-coupling and the directed lithiation as key reactions.
