1089722-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1089722-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,9,7,2 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1089722-77:
(9*1)+(8*0)+(7*8)+(6*9)+(5*7)+(4*2)+(3*2)+(2*7)+(1*7)=189
189 % 10 = 9
So 1089722-77-9 is a valid CAS Registry Number.
