Check Digit Verification of cas no
The CAS Registry Mumber 21072-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,7 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21072-69:
(7*2)+(6*1)+(5*0)+(4*7)+(3*2)+(2*6)+(1*9)=75
75 % 10 = 5
So 21072-69-5 is a valid CAS Registry Number.
