65275-44-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65275-44-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,7 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 65275-44:
(7*6)+(6*5)+(5*2)+(4*7)+(3*5)+(2*4)+(1*4)=137
137 % 10 = 7
So 65275-44-7 is a valid CAS Registry Number.
