1171345-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171345-88-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,3,4 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1171345-88:
(9*1)+(8*1)+(7*7)+(6*1)+(5*3)+(4*4)+(3*5)+(2*8)+(1*8)=142
142 % 10 = 2
So 1171345-88-2 is a valid CAS Registry Number.
