Check Digit Verification of cas no
The CAS Registry Mumber 21680-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,8 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21680-86:
(7*2)+(6*1)+(5*6)+(4*8)+(3*0)+(2*8)+(1*6)=104
104 % 10 = 4
So 21680-86-4 is a valid CAS Registry Number.
