82756-02-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82756-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,5 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82756-02:
(7*8)+(6*2)+(5*7)+(4*5)+(3*6)+(2*0)+(1*2)=143
143 % 10 = 3
So 82756-02-3 is a valid CAS Registry Number.
