Check Digit Verification of cas no
The CAS Registry Mumber 917228-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,2 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 917228-27:
(8*9)+(7*1)+(6*7)+(5*2)+(4*2)+(3*8)+(2*2)+(1*7)=174
174 % 10 = 4
So 917228-27-4 is a valid CAS Registry Number.
