Check Digit Verification of cas no
The CAS Registry Mumber 20071-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20071-04:
(7*2)+(6*0)+(5*0)+(4*7)+(3*1)+(2*0)+(1*4)=49
49 % 10 = 9
So 20071-04-9 is a valid CAS Registry Number.
