Check Digit Verification of cas no
The CAS Registry Mumber 21308-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,0 and 8 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21308-79:
(7*2)+(6*1)+(5*3)+(4*0)+(3*8)+(2*7)+(1*9)=82
82 % 10 = 2
So 21308-79-2 is a valid CAS Registry Number.
