Check Digit Verification of cas no
The CAS Registry Mumber 138040-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,4 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138040-18:
(8*1)+(7*3)+(6*8)+(5*0)+(4*4)+(3*0)+(2*1)+(1*8)=103
103 % 10 = 3
So 138040-18-3 is a valid CAS Registry Number.
