103025-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103025-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,0,2 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103025-50:
(8*1)+(7*0)+(6*3)+(5*0)+(4*2)+(3*5)+(2*5)+(1*0)=59
59 % 10 = 9
So 103025-50-9 is a valid CAS Registry Number.
