82071-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82071-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,7 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82071-34:
(7*8)+(6*2)+(5*0)+(4*7)+(3*1)+(2*3)+(1*4)=109
109 % 10 = 9
So 82071-34-9 is a valid CAS Registry Number.
