1173203-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173203-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,2,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1173203-67:
(9*1)+(8*1)+(7*7)+(6*3)+(5*2)+(4*0)+(3*3)+(2*6)+(1*7)=122
122 % 10 = 2
So 1173203-67-2 is a valid CAS Registry Number.
