438000-89-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 438000-89-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,0,0 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 438000-89:
(8*4)+(7*3)+(6*8)+(5*0)+(4*0)+(3*0)+(2*8)+(1*9)=126
126 % 10 = 6
So 438000-89-6 is a valid CAS Registry Number.
