99217-68-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99217-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,1 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99217-68:
(7*9)+(6*9)+(5*2)+(4*1)+(3*7)+(2*6)+(1*8)=172
172 % 10 = 2
So 99217-68-2 is a valid CAS Registry Number.

Broussochalcones A (BCA, 1) and B (BCB, 2) are major bioactive constituents isolated from Broussonetia papyrifera, a polyphenol-rich plant belonging to the family Moraceae. Due to their low yields from natural sources, BCA (1) and BCB (2) were prepared sy
