1038865-99-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1038865-99-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,8,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1038865-99:
(9*1)+(8*0)+(7*3)+(6*8)+(5*8)+(4*6)+(3*5)+(2*9)+(1*9)=184
184 % 10 = 4
So 1038865-99-4 is a valid CAS Registry Number.
