67863-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67863-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,6 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67863-86:
(7*6)+(6*7)+(5*8)+(4*6)+(3*3)+(2*8)+(1*6)=179
179 % 10 = 9
So 67863-86-9 is a valid CAS Registry Number.
