Check Digit Verification of cas no
The CAS Registry Mumber 117573-52-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,7 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117573-52:
(8*1)+(7*1)+(6*7)+(5*5)+(4*7)+(3*3)+(2*5)+(1*2)=131
131 % 10 = 1
So 117573-52-1 is a valid CAS Registry Number.
