129228-64-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129228-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,2 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129228-64:
(8*1)+(7*2)+(6*9)+(5*2)+(4*2)+(3*8)+(2*6)+(1*4)=134
134 % 10 = 4
So 129228-64-4 is a valid CAS Registry Number.
