874947-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874947-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,9,4 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 874947-55:
(8*8)+(7*7)+(6*4)+(5*9)+(4*4)+(3*7)+(2*5)+(1*5)=234
234 % 10 = 4
So 874947-55-4 is a valid CAS Registry Number.
