Check Digit Verification of cas no
The CAS Registry Mumber 175202-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,0 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 175202-57:
(8*1)+(7*7)+(6*5)+(5*2)+(4*0)+(3*2)+(2*5)+(1*7)=120
120 % 10 = 0
So 175202-57-0 is a valid CAS Registry Number.
