86299-47-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86299-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,9 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86299-47:
(7*8)+(6*6)+(5*2)+(4*9)+(3*9)+(2*4)+(1*7)=180
180 % 10 = 0
So 86299-47-0 is a valid CAS Registry Number.
