Check Digit Verification of cas no
The CAS Registry Mumber 123346-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123346-89:
(8*1)+(7*2)+(6*3)+(5*3)+(4*4)+(3*6)+(2*8)+(1*9)=114
114 % 10 = 4
So 123346-89-4 is a valid CAS Registry Number.
