Check Digit Verification of cas no
The CAS Registry Mumber 110821-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,8,2 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110821-40:
(8*1)+(7*1)+(6*0)+(5*8)+(4*2)+(3*1)+(2*4)+(1*0)=74
74 % 10 = 4
So 110821-40-4 is a valid CAS Registry Number.
