Check Digit Verification of cas no
The CAS Registry Mumber 145931-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,9,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145931-52:
(8*1)+(7*4)+(6*5)+(5*9)+(4*3)+(3*1)+(2*5)+(1*2)=138
138 % 10 = 8
So 145931-52-8 is a valid CAS Registry Number.
