Check Digit Verification of cas no
The CAS Registry Mumber 1426317-25-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,3,1 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1426317-25:
(9*1)+(8*4)+(7*2)+(6*6)+(5*3)+(4*1)+(3*7)+(2*2)+(1*5)=140
140 % 10 = 0
So 1426317-25-0 is a valid CAS Registry Number.

Enantioselective total syntheses of plectosphaeroic acids B and C
Jabri, Salman Y.,Overman, Larry E.
, p. 8766 - 8788 (2013)
Evolution of the synthetic strategy that culminated in the first total syntheses of the structurally unique plectosphaeroic acids B (2) and C (3) is described. The successful enantioselective route to (+)-2 and (+)-3 proceeds in 6 and 11 steps from the kn
