1309453-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1309453-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,5 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1309453-81:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*5)+(3*3)+(2*8)+(1*1)=153
153 % 10 = 3
So 1309453-81-3 is a valid CAS Registry Number.
