Check Digit Verification of cas no
The CAS Registry Mumber 132755-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,7,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 132755-25:
(8*1)+(7*3)+(6*2)+(5*7)+(4*5)+(3*5)+(2*2)+(1*5)=120
120 % 10 = 0
So 132755-25-0 is a valid CAS Registry Number.
