Check Digit Verification of cas no
The CAS Registry Mumber 844901-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,9,0 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 844901-75:
(8*8)+(7*4)+(6*4)+(5*9)+(4*0)+(3*1)+(2*7)+(1*5)=183
183 % 10 = 3
So 844901-75-3 is a valid CAS Registry Number.
