Check Digit Verification of cas no
The CAS Registry Mumber 123878-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,7 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123878-18:
(8*1)+(7*2)+(6*3)+(5*8)+(4*7)+(3*8)+(2*1)+(1*8)=142
142 % 10 = 2
So 123878-18-2 is a valid CAS Registry Number.
