91547-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91547-44-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,4 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91547-44:
(7*9)+(6*1)+(5*5)+(4*4)+(3*7)+(2*4)+(1*4)=143
143 % 10 = 3
So 91547-44-3 is a valid CAS Registry Number.
