1313511-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1313511-73-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,5,1 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1313511-73:
(9*1)+(8*3)+(7*1)+(6*3)+(5*5)+(4*1)+(3*1)+(2*7)+(1*3)=107
107 % 10 = 7
So 1313511-73-7 is a valid CAS Registry Number.
