189500-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189500-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,5,0 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189500-67:
(8*1)+(7*8)+(6*9)+(5*5)+(4*0)+(3*0)+(2*6)+(1*7)=162
162 % 10 = 2
So 189500-67-2 is a valid CAS Registry Number.
