Check Digit Verification of cas no
The CAS Registry Mumber 42221-49-8 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, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42221-49:
(7*4)+(6*2)+(5*2)+(4*2)+(3*1)+(2*4)+(1*9)=78
78 % 10 = 8
So 42221-49-8 is a valid CAS Registry Number.
