1312945-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312945-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,4 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1312945-31:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*4)+(3*5)+(2*3)+(1*1)=135
135 % 10 = 5
So 1312945-31-5 is a valid CAS Registry Number.
