662166-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 662166-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,2,1,6 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 662166-03:
(8*6)+(7*6)+(6*2)+(5*1)+(4*6)+(3*6)+(2*0)+(1*3)=152
152 % 10 = 2
So 662166-03-2 is a valid CAS Registry Number.
