81478-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81478-16-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,7 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81478-16:
(7*8)+(6*1)+(5*4)+(4*7)+(3*8)+(2*1)+(1*6)=142
142 % 10 = 2
So 81478-16-2 is a valid CAS Registry Number.
