Check Digit Verification of cas no
The CAS Registry Mumber 575444-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,5,4,4 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 575444-10:
(8*5)+(7*7)+(6*5)+(5*4)+(4*4)+(3*4)+(2*1)+(1*0)=169
169 % 10 = 9
So 575444-10-9 is a valid CAS Registry Number.
