73872-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73872-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,7 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73872-19:
(7*7)+(6*3)+(5*8)+(4*7)+(3*2)+(2*1)+(1*9)=152
152 % 10 = 2
So 73872-19-2 is a valid CAS Registry Number.
