Check Digit Verification of cas no
The CAS Registry Mumber 100231-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 100231-18:
(8*1)+(7*0)+(6*0)+(5*2)+(4*3)+(3*1)+(2*1)+(1*8)=43
43 % 10 = 3
So 100231-18-3 is a valid CAS Registry Number.
