86670-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86670-39-5 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, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86670-39:
(7*8)+(6*6)+(5*6)+(4*7)+(3*0)+(2*3)+(1*9)=165
165 % 10 = 5
So 86670-39-5 is a valid CAS Registry Number.
