67886-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67886-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,8 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67886-41:
(7*6)+(6*7)+(5*8)+(4*8)+(3*6)+(2*4)+(1*1)=183
183 % 10 = 3
So 67886-41-3 is a valid CAS Registry Number.
