86840-06-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86840-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,8,4 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 86840-06:
(7*8)+(6*6)+(5*8)+(4*4)+(3*0)+(2*0)+(1*6)=154
154 % 10 = 4
So 86840-06-4 is a valid CAS Registry Number.
