Check Digit Verification of cas no
The CAS Registry Mumber 83049-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,4 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 83049-35:
(7*8)+(6*3)+(5*0)+(4*4)+(3*9)+(2*3)+(1*5)=128
128 % 10 = 8
So 83049-35-8 is a valid CAS Registry Number.
