Check Digit Verification of cas no
The CAS Registry Mumber 21520-85-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,2 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21520-85:
(7*2)+(6*1)+(5*5)+(4*2)+(3*0)+(2*8)+(1*5)=74
74 % 10 = 4
So 21520-85-4 is a valid CAS Registry Number.
