183503-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183503-12-0 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 183503-12:
(8*1)+(7*8)+(6*3)+(5*5)+(4*0)+(3*3)+(2*1)+(1*2)=120
120 % 10 = 0
So 183503-12-0 is a valid CAS Registry Number.
