1340481-93-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1340481-93-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,8 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1340481-93:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*8)+(3*1)+(2*9)+(1*3)=137
137 % 10 = 7
So 1340481-93-7 is a valid CAS Registry Number.
