381689-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 381689-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,1,6,8 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 381689-24:
(8*3)+(7*8)+(6*1)+(5*6)+(4*8)+(3*9)+(2*2)+(1*4)=183
183 % 10 = 3
So 381689-24-3 is a valid CAS Registry Number.
