Check Digit Verification of cas no
The CAS Registry Mumber 302554-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,2,5,5 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 302554-19:
(8*3)+(7*0)+(6*2)+(5*5)+(4*5)+(3*4)+(2*1)+(1*9)=104
104 % 10 = 4
So 302554-19-4 is a valid CAS Registry Number.
