87672-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87672-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,7 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87672-99:
(7*8)+(6*7)+(5*6)+(4*7)+(3*2)+(2*9)+(1*9)=189
189 % 10 = 9
So 87672-99-9 is a valid CAS Registry Number.
