Check Digit Verification of cas no

The CAS Registry Mumber 1146732-16-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,6,7,3 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1146732-16:
(9*1)+(8*1)+(7*4)+(6*6)+(5*7)+(4*3)+(3*2)+(2*1)+(1*6)=142
142 % 10 = 2
So 1146732-16-2 is a valid CAS Registry Number.

Synthesis of nonsymmetrical 5-Aryl-2-indolopyrrole derivatives via controlled mono Suzuki-Miyaura cross-coupling on N-Boc-2,5-dibromopyrrole

Beaumard, Floriane,Dauban, Philippe,Dodd, Robert H.

experimental part, p. 4033 - 4042 (2011/02/22)

The first example of mono Suzuki-Miyaura cross-coupling of N-Boc-2,5-dibromopyrrole with a boronic acid (indol-2-ylboronic acid) is reported. The resulting 2-indolyl-5-bromopyrrole derivative was in turn coupled with a variety of aryl- or heteroarylboronic acids thereby providing the corresponding non-symmetrical 2,5-disubstituted pyrroles in good to excellent yields. The tert-butoxycarbonyl (Boc) groups could be easily removed to give the completely deprotected products. Georg Thieme Verlag Stuttgart - New York.
