75933-86-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75933-86-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,3 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 75933-86:
(7*7)+(6*5)+(5*9)+(4*3)+(3*3)+(2*8)+(1*6)=167
167 % 10 = 7
So 75933-86-7 is a valid CAS Registry Number.
