74458-90-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74458-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74458-90:
(7*7)+(6*4)+(5*4)+(4*5)+(3*8)+(2*9)+(1*0)=155
155 % 10 = 5
So 74458-90-5 is a valid CAS Registry Number.
