1090-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1090-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 1090-89:
(6*1)+(5*0)+(4*9)+(3*0)+(2*8)+(1*9)=67
67 % 10 = 7
So 1090-89-7 is a valid CAS Registry Number.
