1191080-94-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191080-94-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,0,8 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1191080-94:
(9*1)+(8*1)+(7*9)+(6*1)+(5*0)+(4*8)+(3*0)+(2*9)+(1*4)=140
140 % 10 = 0
So 1191080-94-0 is a valid CAS Registry Number.
