37458-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37458-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,4,5 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 37458-56:
(7*3)+(6*7)+(5*4)+(4*5)+(3*8)+(2*5)+(1*6)=143
143 % 10 = 3
So 37458-56-3 is a valid CAS Registry Number.
