1197175-26-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197175-26-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,1,7 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1197175-26:
(9*1)+(8*1)+(7*9)+(6*7)+(5*1)+(4*7)+(3*5)+(2*2)+(1*6)=180
180 % 10 = 0
So 1197175-26-0 is a valid CAS Registry Number.
