660870-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 660870-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,0,8,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 660870-77:
(8*6)+(7*6)+(6*0)+(5*8)+(4*7)+(3*0)+(2*7)+(1*7)=179
179 % 10 = 9
So 660870-77-9 is a valid CAS Registry Number.
