Check Digit Verification of cas no
The CAS Registry Mumber 21708-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,0 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 21708-77:
(7*2)+(6*1)+(5*7)+(4*0)+(3*8)+(2*7)+(1*7)=100
100 % 10 = 0
So 21708-77-0 is a valid CAS Registry Number.
