128741-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128741-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128741-55:
(8*1)+(7*2)+(6*8)+(5*7)+(4*4)+(3*1)+(2*5)+(1*5)=139
139 % 10 = 9
So 128741-55-9 is a valid CAS Registry Number.
