74872-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74872-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,7 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74872-75:
(7*7)+(6*4)+(5*8)+(4*7)+(3*2)+(2*7)+(1*5)=166
166 % 10 = 6
So 74872-75-6 is a valid CAS Registry Number.
