Check Digit Verification of cas no
The CAS Registry Mumber 74441-05-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,4 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74441-05:
(7*7)+(6*4)+(5*4)+(4*4)+(3*1)+(2*0)+(1*5)=117
117 % 10 = 7
So 74441-05-7 is a valid CAS Registry Number.
