344872-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344872-37-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,7 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 344872-37:
(8*3)+(7*4)+(6*4)+(5*8)+(4*7)+(3*2)+(2*3)+(1*7)=163
163 % 10 = 3
So 344872-37-3 is a valid CAS Registry Number.
