1131303-30-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131303-30-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,3,0 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1131303-30:
(9*1)+(8*1)+(7*3)+(6*1)+(5*3)+(4*0)+(3*3)+(2*3)+(1*0)=74
74 % 10 = 4
So 1131303-30-4 is a valid CAS Registry Number.
