281195-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 281195-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,1,1,9 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 281195-16:
(8*2)+(7*8)+(6*1)+(5*1)+(4*9)+(3*5)+(2*1)+(1*6)=142
142 % 10 = 2
So 281195-16-2 is a valid CAS Registry Number.
