Check Digit Verification of cas no
The CAS Registry Mumber 42221-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,2 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 42221-52:
(7*4)+(6*2)+(5*2)+(4*2)+(3*1)+(2*5)+(1*2)=73
73 % 10 = 3
So 42221-52-3 is a valid CAS Registry Number.
