1393107-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1393107-83-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,1,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1393107-83:
(9*1)+(8*3)+(7*9)+(6*3)+(5*1)+(4*0)+(3*7)+(2*8)+(1*3)=159
159 % 10 = 9
So 1393107-83-9 is a valid CAS Registry Number.
