Check Digit Verification of cas no
The CAS Registry Mumber 21279-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,7 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21279-62:
(7*2)+(6*1)+(5*2)+(4*7)+(3*9)+(2*6)+(1*2)=99
99 % 10 = 9
So 21279-62-9 is a valid CAS Registry Number.
