Check Digit Verification of cas no
The CAS Registry Mumber 133519-75-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,1 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133519-75:
(8*1)+(7*3)+(6*3)+(5*5)+(4*1)+(3*9)+(2*7)+(1*5)=122
122 % 10 = 2
So 133519-75-2 is a valid CAS Registry Number.
