81613-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81613-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,1 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81613-46:
(7*8)+(6*1)+(5*6)+(4*1)+(3*3)+(2*4)+(1*6)=119
119 % 10 = 9
So 81613-46-9 is a valid CAS Registry Number.
