Check Digit Verification of cas no
The CAS Registry Mumber 918972-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,9,7 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 918972-57:
(8*9)+(7*1)+(6*8)+(5*9)+(4*7)+(3*2)+(2*5)+(1*7)=223
223 % 10 = 3
So 918972-57-3 is a valid CAS Registry Number.
