Check Digit Verification of cas no

The CAS Registry Mumber 1305340-50-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,5,3,4 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1305340-50:
(9*1)+(8*3)+(7*0)+(6*5)+(5*3)+(4*4)+(3*0)+(2*5)+(1*0)=104
104 % 10 = 4
So 1305340-50-4 is a valid CAS Registry Number.

Synthesis of (-)-viriditoxin: A 6,6′-binaphthopyran-2-one that targets the bacterial cell division protein FtsZ

Park, Young Sam,Grove, Charles I.,Gonzalez-Lopez, Marcos,Urgaonkar, Sameer,Fettinger, James C.,Shaw, Jared T.

, p. 3730 - 3733 (2011/05/15)

(Chemical Equation Presented) Remote control: Vanadium catalysts provide the key to synthesizing the bacteria-fighting natural product viriditoxin. An achiral catalyst shows modest levels of remote diastereocontrol induced by the lactone stereogenic center and chiral catalysts can be used to enhance or reverse this inherent selectivity.
