69538-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69538-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,3 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 69538-99:
(7*6)+(6*9)+(5*5)+(4*3)+(3*8)+(2*9)+(1*9)=184
184 % 10 = 4
So 69538-99-4 is a valid CAS Registry Number.
