Check Digit Verification of cas no
The CAS Registry Mumber 3011-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,1 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3011-82:
(6*3)+(5*0)+(4*1)+(3*1)+(2*8)+(1*2)=43
43 % 10 = 3
So 3011-82-3 is a valid CAS Registry Number.
