1392104-03-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1392104-03-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,1,0 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1392104-03:
(9*1)+(8*3)+(7*9)+(6*2)+(5*1)+(4*0)+(3*4)+(2*0)+(1*3)=128
128 % 10 = 8
So 1392104-03-8 is a valid CAS Registry Number.
