1180611-42-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1180611-42-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,0,6,1 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1180611-42:
(9*1)+(8*1)+(7*8)+(6*0)+(5*6)+(4*1)+(3*1)+(2*4)+(1*2)=120
120 % 10 = 0
So 1180611-42-0 is a valid CAS Registry Number.
