Check Digit Verification of cas no
The CAS Registry Mumber 180028-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,0,2 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 180028-92:
(8*1)+(7*8)+(6*0)+(5*0)+(4*2)+(3*8)+(2*9)+(1*2)=116
116 % 10 = 6
So 180028-92-6 is a valid CAS Registry Number.
