Check Digit Verification of cas no
The CAS Registry Mumber 123846-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,4 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123846-68:
(8*1)+(7*2)+(6*3)+(5*8)+(4*4)+(3*6)+(2*6)+(1*8)=134
134 % 10 = 4
So 123846-68-4 is a valid CAS Registry Number.
