179258-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 179258-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,2,5 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 179258-52:
(8*1)+(7*7)+(6*9)+(5*2)+(4*5)+(3*8)+(2*5)+(1*2)=177
177 % 10 = 7
So 179258-52-7 is a valid CAS Registry Number.
