Check Digit Verification of cas no

The CAS Registry Mumber 856966-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,9,6 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 856966-91:
(8*8)+(7*5)+(6*6)+(5*9)+(4*6)+(3*6)+(2*9)+(1*1)=241
241 % 10 = 1
So 856966-91-1 is a valid CAS Registry Number.

Metallation in connection with cross-coupling reactions. Coupling of hindered aryls for the synthesis of 4-phenylpyridines as part of Streptonigrin and Lavendamycin analogues

Godard,Rocca,Pomel,Thomas-Dit-Dumont,Rovera,Thaburet,Marsais,Queguiner

, p. 25 - 36 (2007/10/03)

The synthesis of the C-D ring system of Streptonigrin and Lavendamycln alkaloid analogues by cross-coupling under Suzuki's conditions has been studied. Steric hindrance is the main problem. It has been solved either by using strong bases or working in a sealed tube under pressure.
