183503-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183503-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,5,0 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 183503-15:
(8*1)+(7*8)+(6*3)+(5*5)+(4*0)+(3*3)+(2*1)+(1*5)=123
123 % 10 = 3
So 183503-15-3 is a valid CAS Registry Number.
