Check Digit Verification of cas no
The CAS Registry Mumber 22172-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,7 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 22172-17:
(7*2)+(6*2)+(5*1)+(4*7)+(3*2)+(2*1)+(1*7)=74
74 % 10 = 4
So 22172-17-4 is a valid CAS Registry Number.
