Definition
ChEBI: A member of the class of cleistanthins that is the 4-O-3,4-di-O-methyl-beta-D-xylopyranoside of 1,3-dihydronaphtho[2,3-c]furan-4-ol which is substituted by an oxo group at
position 1, methoxy groups at positions 6 and 7, and a 1,3-benzodioxol-5-yl group at position 9. It is one of the toxic principles in Cleistanthus collinus.
Check Digit Verification of cas no
The CAS Registry Mumber 25047-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,4 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 25047-48:
(7*2)+(6*5)+(5*0)+(4*4)+(3*7)+(2*4)+(1*8)=97
97 % 10 = 7
So 25047-48-7 is a valid CAS Registry Number.
