83700-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83700-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,0 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83700-71:
(7*8)+(6*3)+(5*7)+(4*0)+(3*0)+(2*7)+(1*1)=124
124 % 10 = 4
So 83700-71-4 is a valid CAS Registry Number.
