Check Digit Verification of cas no
The CAS Registry Mumber 2402-91-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2402-91:
(6*2)+(5*4)+(4*0)+(3*2)+(2*9)+(1*1)=57
57 % 10 = 7
So 2402-91-7 is a valid CAS Registry Number.

Convergent stereoselective synthesis of the visual pigment A2E
Sicre, Cristina,Cid, M. Magdalena
, p. 5737 - 5739 (2005)
(Chemical Equation Presented) A stereoselective total synthesis of the visual pigment A2E has been achieved with use of palladium-catalyzed cross-coupling reactions in all key steps: a regioselective Suzuki or Negishi coupling of 2,4-dibromopyridine, a Sonogashira reaction, and a double Stille cross-coupling to complete the bispolyenyl skeleton.
