Check Digit Verification of cas no
The CAS Registry Mumber 83949-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83949-45:
(7*8)+(6*3)+(5*9)+(4*4)+(3*9)+(2*4)+(1*5)=175
175 % 10 = 5
So 83949-45-5 is a valid CAS Registry Number.
