1181491-60-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1181491-60-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,1,4,9 and 1 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1181491-60:
(9*1)+(8*1)+(7*8)+(6*1)+(5*4)+(4*9)+(3*1)+(2*6)+(1*0)=150
150 % 10 = 0
So 1181491-60-0 is a valid CAS Registry Number.
