Check Digit Verification of cas no
The CAS Registry Mumber 123217-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,1 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123217-58:
(8*1)+(7*2)+(6*3)+(5*2)+(4*1)+(3*7)+(2*5)+(1*8)=93
93 % 10 = 3
So 123217-58-3 is a valid CAS Registry Number.
