Check Digit Verification of cas no
The CAS Registry Mumber 172337-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,3,3 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172337-58:
(8*1)+(7*7)+(6*2)+(5*3)+(4*3)+(3*7)+(2*5)+(1*8)=135
135 % 10 = 5
So 172337-58-5 is a valid CAS Registry Number.
