1283598-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1283598-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,3,5,9 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1283598-89:
(9*1)+(8*2)+(7*8)+(6*3)+(5*5)+(4*9)+(3*8)+(2*8)+(1*9)=209
209 % 10 = 9
So 1283598-89-9 is a valid CAS Registry Number.
