Check Digit Verification of cas no
The CAS Registry Mumber 16265-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,6 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 16265-56:
(7*1)+(6*6)+(5*2)+(4*6)+(3*5)+(2*5)+(1*6)=108
108 % 10 = 8
So 16265-56-8 is a valid CAS Registry Number.
