Check Digit Verification of cas no
The CAS Registry Mumber 181872-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,8,7 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 181872-90:
(8*1)+(7*8)+(6*1)+(5*8)+(4*7)+(3*2)+(2*9)+(1*0)=162
162 % 10 = 2
So 181872-90-2 is a valid CAS Registry Number.
