1176080-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1176080-20-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,6,0,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1176080-20:
(9*1)+(8*1)+(7*7)+(6*6)+(5*0)+(4*8)+(3*0)+(2*2)+(1*0)=138
138 % 10 = 8
So 1176080-20-8 is a valid CAS Registry Number.
