169128-74-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 169128-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,1,2 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 169128-74:
(8*1)+(7*6)+(6*9)+(5*1)+(4*2)+(3*8)+(2*7)+(1*4)=159
159 % 10 = 9
So 169128-74-9 is a valid CAS Registry Number.
