331852-89-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331852-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,8,5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 331852-89:
(8*3)+(7*3)+(6*1)+(5*8)+(4*5)+(3*2)+(2*8)+(1*9)=142
142 % 10 = 2
So 331852-89-2 is a valid CAS Registry Number.
