Check Digit Verification of cas no
The CAS Registry Mumber 492459-29-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,2,4,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 492459-29:
(8*4)+(7*9)+(6*2)+(5*4)+(4*5)+(3*9)+(2*2)+(1*9)=187
187 % 10 = 7
So 492459-29-7 is a valid CAS Registry Number.
