1038923-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1038923-75-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,8,9,2 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1038923-75:
(9*1)+(8*0)+(7*3)+(6*8)+(5*9)+(4*2)+(3*3)+(2*7)+(1*5)=159
159 % 10 = 9
So 1038923-75-9 is a valid CAS Registry Number.
