129413-28-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129413-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,1 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129413-28:
(8*1)+(7*2)+(6*9)+(5*4)+(4*1)+(3*3)+(2*2)+(1*8)=121
121 % 10 = 1
So 129413-28-1 is a valid CAS Registry Number.
