Check Digit Verification of cas no
The CAS Registry Mumber 30911-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,9,1 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 30911-72:
(7*3)+(6*0)+(5*9)+(4*1)+(3*1)+(2*7)+(1*2)=89
89 % 10 = 9
So 30911-72-9 is a valid CAS Registry Number.
