1172604-02-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1172604-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,6,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1172604-02:
(9*1)+(8*1)+(7*7)+(6*2)+(5*6)+(4*0)+(3*4)+(2*0)+(1*2)=122
122 % 10 = 2
So 1172604-02-2 is a valid CAS Registry Number.
