Check Digit Verification of cas no
The CAS Registry Mumber 124392-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,3,9 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124392-67:
(8*1)+(7*2)+(6*4)+(5*3)+(4*9)+(3*2)+(2*6)+(1*7)=122
122 % 10 = 2
So 124392-67-2 is a valid CAS Registry Number.
