Check Digit Verification of cas no
The CAS Registry Mumber 135330-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,3 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135330-75:
(8*1)+(7*3)+(6*5)+(5*3)+(4*3)+(3*0)+(2*7)+(1*5)=105
105 % 10 = 5
So 135330-75-5 is a valid CAS Registry Number.
