Check Digit Verification of cas no
The CAS Registry Mumber 14220-17-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,2 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14220-17:
(7*1)+(6*4)+(5*2)+(4*2)+(3*0)+(2*1)+(1*7)=58
58 % 10 = 8
So 14220-17-8 is a valid CAS Registry Number.
