Check Digit Verification of cas no
The CAS Registry Mumber 213258-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,2,5 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213258-59:
(8*2)+(7*1)+(6*3)+(5*2)+(4*5)+(3*8)+(2*5)+(1*9)=114
114 % 10 = 4
So 213258-59-4 is a valid CAS Registry Number.
