Check Digit Verification of cas no
The CAS Registry Mumber 612493-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,2,4,9 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 612493-95:
(8*6)+(7*1)+(6*2)+(5*4)+(4*9)+(3*3)+(2*9)+(1*5)=155
155 % 10 = 5
So 612493-95-5 is a valid CAS Registry Number.
