86648-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86648-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86648-77:
(7*8)+(6*6)+(5*6)+(4*4)+(3*8)+(2*7)+(1*7)=183
183 % 10 = 3
So 86648-77-3 is a valid CAS Registry Number.
