181944-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181944-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,9,4 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 181944-74:
(8*1)+(7*8)+(6*1)+(5*9)+(4*4)+(3*4)+(2*7)+(1*4)=161
161 % 10 = 1
So 181944-74-1 is a valid CAS Registry Number.
