Check Digit Verification of cas no
The CAS Registry Mumber 189230-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,3 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189230-41:
(8*1)+(7*8)+(6*9)+(5*2)+(4*3)+(3*0)+(2*4)+(1*1)=149
149 % 10 = 9
So 189230-41-9 is a valid CAS Registry Number.
