Check Digit Verification of cas no
The CAS Registry Mumber 60811-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,8,1 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 60811-21:
(7*6)+(6*0)+(5*8)+(4*1)+(3*1)+(2*2)+(1*1)=94
94 % 10 = 4
So 60811-21-4 is a valid CAS Registry Number.
