86557-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86557-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,5,5 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86557-69:
(7*8)+(6*6)+(5*5)+(4*5)+(3*7)+(2*6)+(1*9)=179
179 % 10 = 9
So 86557-69-9 is a valid CAS Registry Number.
