1173897-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173897-91-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,8,9 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1173897-91:
(9*1)+(8*1)+(7*7)+(6*3)+(5*8)+(4*9)+(3*7)+(2*9)+(1*1)=200
200 % 10 = 0
So 1173897-91-0 is a valid CAS Registry Number.
