172788-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172788-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,8 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172788-91:
(8*1)+(7*7)+(6*2)+(5*7)+(4*8)+(3*8)+(2*9)+(1*1)=179
179 % 10 = 9
So 172788-91-9 is a valid CAS Registry Number.
