74271-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74271-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74271-55:
(7*7)+(6*4)+(5*2)+(4*7)+(3*1)+(2*5)+(1*5)=129
129 % 10 = 9
So 74271-55-9 is a valid CAS Registry Number.
