7491-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7491-76-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7491-76:
(6*7)+(5*4)+(4*9)+(3*1)+(2*7)+(1*6)=121
121 % 10 = 1
So 7491-76-1 is a valid CAS Registry Number.
