289912-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289912-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,1 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 289912-98:
(8*2)+(7*8)+(6*9)+(5*9)+(4*1)+(3*2)+(2*9)+(1*8)=207
207 % 10 = 7
So 289912-98-7 is a valid CAS Registry Number.
