91043-58-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91043-58-2 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 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91043-58:
(7*9)+(6*1)+(5*0)+(4*4)+(3*3)+(2*5)+(1*8)=112
112 % 10 = 2
So 91043-58-2 is a valid CAS Registry Number.
