(3S,8aS)-Decahydro-7α-hydroxy-4aα,5α-dimethyl-3β-(1-methylvinyl)naphthalen-1-one, also known as (+)-Rishitinone or Rishitinone, is a valencane-type sesquiterpene stress metabolite produced in diseased potato tubers. Its structure, including stereochemistry, was confirmed through chemical and spectral analysis, highlighting its role as a biologically relevant compound in plant stress responses.

74299-59-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74299-59-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,9 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74299-59:
(7*7)+(6*4)+(5*2)+(4*9)+(3*9)+(2*5)+(1*9)=165
165 % 10 = 5
So 74299-59-5 is a valid CAS Registry Number.
