872373-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 872373-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,3,7 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 872373-56:
(8*8)+(7*7)+(6*2)+(5*3)+(4*7)+(3*3)+(2*5)+(1*6)=193
193 % 10 = 3
So 872373-56-3 is a valid CAS Registry Number.
