893403-38-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 893403-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,4,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 893403-38:
(8*8)+(7*9)+(6*3)+(5*4)+(4*0)+(3*3)+(2*3)+(1*8)=188
188 % 10 = 8
So 893403-38-8 is a valid CAS Registry Number.
