858666-85-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 858666-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,6,6 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 858666-85:
(8*8)+(7*5)+(6*8)+(5*6)+(4*6)+(3*6)+(2*8)+(1*5)=240
240 % 10 = 0
So 858666-85-0 is a valid CAS Registry Number.
