1340499-01-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1340499-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1340499-01:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*9)+(3*9)+(2*0)+(1*1)=145
145 % 10 = 5
So 1340499-01-5 is a valid CAS Registry Number.
