6181-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6181-21-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,8 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6181-21:
(6*6)+(5*1)+(4*8)+(3*1)+(2*2)+(1*1)=81
81 % 10 = 1
So 6181-21-1 is a valid CAS Registry Number.
