Check Digit Verification of cas no

The CAS Registry Mumber 855631-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,6,3 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 855631-70:
(8*8)+(7*5)+(6*5)+(5*6)+(4*3)+(3*1)+(2*7)+(1*0)=188
188 % 10 = 8
So 855631-70-8 is a valid CAS Registry Number.

Synthesis of functionalized 2-arylthiophenes with triarylbismuths as atom-efficient multicoupling organometallic nucleophiles under palladium catalysis

Rao, Maddali L. N.,Banerjee, Debasis,Dhanorkar, Ritesh J.

supporting information; experimental part, p. 1324 - 1330 (2011/07/07)

Atom-efficient cross-coupling reactions of functionalized 2-bromo- and 2-iodothiophenes have been demonstrated using triarylbismuths as atom-efficient multicoupling organometallic nucleophiles under palladium-catalyzed conditions. These couplings with various functionalized triarylbismuths proceeded smoothly to afford the corresponding functionalized 2-arylthiophenes in high yields. Georg Thieme Verlag Stuttgart · New York.
