Check Digit Verification of cas no
The CAS Registry Mumber 954149-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,4,1,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 954149-05:
(8*9)+(7*5)+(6*4)+(5*1)+(4*4)+(3*9)+(2*0)+(1*5)=184
184 % 10 = 4
So 954149-05-4 is a valid CAS Registry Number.
