86433-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86433-71-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86433-71:
(7*8)+(6*6)+(5*4)+(4*3)+(3*3)+(2*7)+(1*1)=148
148 % 10 = 8
So 86433-71-8 is a valid CAS Registry Number.
