Check Digit Verification of cas no
The CAS Registry Mumber 16547-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,4 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16547-34:
(7*1)+(6*6)+(5*5)+(4*4)+(3*7)+(2*3)+(1*4)=115
115 % 10 = 5
So 16547-34-5 is a valid CAS Registry Number.
