Check Digit Verification of cas no
The CAS Registry Mumber 84170-03-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,1,7 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 84170-03:
(7*8)+(6*4)+(5*1)+(4*7)+(3*0)+(2*0)+(1*3)=116
116 % 10 = 6
So 84170-03-6 is a valid CAS Registry Number.
