Check Digit Verification of cas no
The CAS Registry Mumber 1807520-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1807520-99:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*2)+(3*0)+(2*9)+(1*9)=175
175 % 10 = 5
So 1807520-99-5 is a valid CAS Registry Number.
