Check Digit Verification of cas no

The CAS Registry Mumber 129871-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,7 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129871-28:
(8*1)+(7*2)+(6*9)+(5*8)+(4*7)+(3*1)+(2*2)+(1*8)=159
159 % 10 = 9
So 129871-28-9 is a valid CAS Registry Number.

Palladium Catalysis in Cephalosporin Chemistry: General Methodology for the Synthesis of Cephem Side Chains

Farina, Vittorio,Baker, Stephen R.,Benigni, Daniel A.,Hauck, Sheila I.,Sapino, Chester

, p. 5833 - 5847 (2007/10/02)

We describe in full the palladium-catalyzed coupling of 3-(triflyloxy)cephems with organotin compounds, leading to the synthesis of 3-alkenyl-, 3-alkynyl-, and 3-arylcephems under exceptionally mild conditions.While this approach was not satisfactory for
