74569-91-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74569-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,6 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74569-91:
(7*7)+(6*4)+(5*5)+(4*6)+(3*9)+(2*9)+(1*1)=168
168 % 10 = 8
So 74569-91-8 is a valid CAS Registry Number.
