753003-11-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 753003-11-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,3,0,0 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 753003-11:
(8*7)+(7*5)+(6*3)+(5*0)+(4*0)+(3*3)+(2*1)+(1*1)=121
121 % 10 = 1
So 753003-11-1 is a valid CAS Registry Number.
