669775-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669775-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,7,7 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 669775-19:
(8*6)+(7*6)+(6*9)+(5*7)+(4*7)+(3*5)+(2*1)+(1*9)=233
233 % 10 = 3
So 669775-19-3 is a valid CAS Registry Number.
