Check Digit Verification of cas no
The CAS Registry Mumber 83548-63-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,4 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 83548-63:
(7*8)+(6*3)+(5*5)+(4*4)+(3*8)+(2*6)+(1*3)=154
154 % 10 = 4
So 83548-63-4 is a valid CAS Registry Number.
