81231-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81231-94-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,3 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81231-94:
(7*8)+(6*1)+(5*2)+(4*3)+(3*1)+(2*9)+(1*4)=109
109 % 10 = 9
So 81231-94-9 is a valid CAS Registry Number.
