Check Digit Verification of cas no
The CAS Registry Mumber 202120-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,1,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 202120-06:
(8*2)+(7*0)+(6*2)+(5*1)+(4*2)+(3*0)+(2*0)+(1*6)=47
47 % 10 = 7
So 202120-06-7 is a valid CAS Registry Number.
