371758-71-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 371758-71-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,1,7,5 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 371758-71:
(8*3)+(7*7)+(6*1)+(5*7)+(4*5)+(3*8)+(2*7)+(1*1)=173
173 % 10 = 3
So 371758-71-3 is a valid CAS Registry Number.
