238401-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 238401-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,4,0 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 238401-89:
(8*2)+(7*3)+(6*8)+(5*4)+(4*0)+(3*1)+(2*8)+(1*9)=133
133 % 10 = 3
So 238401-89-3 is a valid CAS Registry Number.
