72493-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72493-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,4,9 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72493-30:
(7*7)+(6*2)+(5*4)+(4*9)+(3*3)+(2*3)+(1*0)=132
132 % 10 = 2
So 72493-30-2 is a valid CAS Registry Number.
