1089958-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1089958-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,9,5 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1089958-80:
(9*1)+(8*0)+(7*8)+(6*9)+(5*9)+(4*5)+(3*8)+(2*8)+(1*0)=224
224 % 10 = 4
So 1089958-80-4 is a valid CAS Registry Number.
