Check Digit Verification of cas no
The CAS Registry Mumber 20929-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,9,2 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.Calculate Digit Verification of CAS Registry Number 20929-84:
(7*2)+(6*0)+(5*9)+(4*2)+(3*9)+(2*8)+(1*4)=114
114 % 10 = 4
So 20929-84-4 is a valid CAS Registry Number.
