78173-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78173-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,7 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78173-92:
(7*7)+(6*8)+(5*1)+(4*7)+(3*3)+(2*9)+(1*2)=159
159 % 10 = 9
So 78173-92-9 is a valid CAS Registry Number.
