Check Digit Verification of cas no
The CAS Registry Mumber 18972-56-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,7 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18972-56:
(7*1)+(6*8)+(5*9)+(4*7)+(3*2)+(2*5)+(1*6)=150
150 % 10 = 0
So 18972-56-0 is a valid CAS Registry Number.
