37880-24-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37880-24-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,8,8 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 37880-24:
(7*3)+(6*7)+(5*8)+(4*8)+(3*0)+(2*2)+(1*4)=143
143 % 10 = 3
So 37880-24-3 is a valid CAS Registry Number.
