1345138-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1345138-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,1,3 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1345138-69:
(9*1)+(8*3)+(7*4)+(6*5)+(5*1)+(4*3)+(3*8)+(2*6)+(1*9)=153
153 % 10 = 3
So 1345138-69-3 is a valid CAS Registry Number.
