21708-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21708-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,0 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.Calculate Digit Verification of CAS Registry Number 21708-34:
(7*2)+(6*1)+(5*7)+(4*0)+(3*8)+(2*3)+(1*4)=89
89 % 10 = 9
So 21708-34-9 is a valid CAS Registry Number.
