86670-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86670-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 86670-62:
(7*8)+(6*6)+(5*6)+(4*7)+(3*0)+(2*6)+(1*2)=164
164 % 10 = 4
So 86670-62-4 is a valid CAS Registry Number.
