Check Digit Verification of cas no
The CAS Registry Mumber 189278-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189278-12:
(8*1)+(7*8)+(6*9)+(5*2)+(4*7)+(3*8)+(2*1)+(1*2)=184
184 % 10 = 4
So 189278-12-4 is a valid CAS Registry Number.
