37703-82-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 37703-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,7,0 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 37703-82:
(7*3)+(6*7)+(5*7)+(4*0)+(3*3)+(2*8)+(1*2)=125
125 % 10 = 5
So 37703-82-5 is a valid CAS Registry Number.
