Check Digit Verification of cas no

The CAS Registry Mumber 103963-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,6 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 103963-35:
(8*1)+(7*0)+(6*3)+(5*9)+(4*6)+(3*3)+(2*3)+(1*5)=115
115 % 10 = 5
So 103963-35-5 is a valid CAS Registry Number.

Palladium Catalysed Cross-Coupling of Vinyl Triflates with 9-Alkyl-9-borobicyclononanes. Total Synthesis of (-)-Isoseiridine.

Grigg, Ronald,Kennewell, Peter,Savic, Vladimir

, p. 5489 - 5494 (2007/10/02)

Pd(O) Catalysed cross-coupling of butenolide-3-triflates to 9-alkyl-9-borobicyclononanes occurs in moderate to good yield and tolerates a range of functionality.Application of this methodology combined with addition of diethylzinc to a butenolide aldehyde in the presence of an ephedrine derivative leads to a 3-step synthesis of (-)-isoseiridine with 88percent e.e. in good yield.
