289890-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289890-42-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,8,9 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 289890-42:
(8*2)+(7*8)+(6*9)+(5*8)+(4*9)+(3*0)+(2*4)+(1*2)=212
212 % 10 = 2
So 289890-42-2 is a valid CAS Registry Number.
