17187-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17187-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,8 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17187-55:
(7*1)+(6*7)+(5*1)+(4*8)+(3*7)+(2*5)+(1*5)=122
122 % 10 = 2
So 17187-55-2 is a valid CAS Registry Number.
