128775-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128775-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128775-57:
(8*1)+(7*2)+(6*8)+(5*7)+(4*7)+(3*5)+(2*5)+(1*7)=165
165 % 10 = 5
So 128775-57-5 is a valid CAS Registry Number.
