179925-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 179925-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,9,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 179925-89:
(8*1)+(7*7)+(6*9)+(5*9)+(4*2)+(3*5)+(2*8)+(1*9)=204
204 % 10 = 4
So 179925-89-4 is a valid CAS Registry Number.
