175892-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 175892-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,8,9 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 175892-98:
(8*1)+(7*7)+(6*5)+(5*8)+(4*9)+(3*2)+(2*9)+(1*8)=195
195 % 10 = 5
So 175892-98-5 is a valid CAS Registry Number.
