213468-59-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 213468-59-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,4,6 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213468-59:
(8*2)+(7*1)+(6*3)+(5*4)+(4*6)+(3*8)+(2*5)+(1*9)=128
128 % 10 = 8
So 213468-59-8 is a valid CAS Registry Number.
