203455-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 203455-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,4,5 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 203455-63:
(8*2)+(7*0)+(6*3)+(5*4)+(4*5)+(3*5)+(2*6)+(1*3)=104
104 % 10 = 4
So 203455-63-4 is a valid CAS Registry Number.
