Check Digit Verification of cas no
The CAS Registry Mumber 3051-11-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,5 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3051-11:
(6*3)+(5*0)+(4*5)+(3*1)+(2*1)+(1*1)=44
44 % 10 = 4
So 3051-11-4 is a valid CAS Registry Number.
