Check Digit Verification of cas no
The CAS Registry Mumber 223918-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,9,1 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 223918-26:
(8*2)+(7*2)+(6*3)+(5*9)+(4*1)+(3*8)+(2*2)+(1*6)=131
131 % 10 = 1
So 223918-26-1 is a valid CAS Registry Number.
