128229-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128229-75-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,2 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128229-75:
(8*1)+(7*2)+(6*8)+(5*2)+(4*2)+(3*9)+(2*7)+(1*5)=134
134 % 10 = 4
So 128229-75-4 is a valid CAS Registry Number.
