4775-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4775-36-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,7 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.Calculate Digit Verification of CAS Registry Number 4775-36:
(6*4)+(5*7)+(4*7)+(3*5)+(2*3)+(1*6)=114
114 % 10 = 4
So 4775-36-4 is a valid CAS Registry Number.
