125329-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125329-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,2 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125329-33:
(8*1)+(7*2)+(6*5)+(5*3)+(4*2)+(3*9)+(2*3)+(1*3)=111
111 % 10 = 1
So 125329-33-1 is a valid CAS Registry Number.
