1189568-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189568-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,5,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1189568-91:
(9*1)+(8*1)+(7*8)+(6*9)+(5*5)+(4*6)+(3*8)+(2*9)+(1*1)=219
219 % 10 = 9
So 1189568-91-9 is a valid CAS Registry Number.
