81202-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81202-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81202-76:
(7*8)+(6*1)+(5*2)+(4*0)+(3*2)+(2*7)+(1*6)=98
98 % 10 = 8
So 81202-76-8 is a valid CAS Registry Number.
