91047-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91047-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91047-81:
(7*9)+(6*1)+(5*0)+(4*4)+(3*7)+(2*8)+(1*1)=123
123 % 10 = 3
So 91047-81-3 is a valid CAS Registry Number.
