1345674-40-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1345674-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,6,7 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1345674-40:
(9*1)+(8*3)+(7*4)+(6*5)+(5*6)+(4*7)+(3*4)+(2*4)+(1*0)=169
169 % 10 = 9
So 1345674-40-9 is a valid CAS Registry Number.
