666833-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666833-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,8,3 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 666833-85:
(8*6)+(7*6)+(6*6)+(5*8)+(4*3)+(3*3)+(2*8)+(1*5)=208
208 % 10 = 8
So 666833-85-8 is a valid CAS Registry Number.
