1161880-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1161880-90-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,1,8,8 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1161880-90:
(9*1)+(8*1)+(7*6)+(6*1)+(5*8)+(4*8)+(3*0)+(2*9)+(1*0)=155
155 % 10 = 5
So 1161880-90-5 is a valid CAS Registry Number.
