682771-92-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 682771-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,7,7 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 682771-92:
(8*6)+(7*8)+(6*2)+(5*7)+(4*7)+(3*1)+(2*9)+(1*2)=202
202 % 10 = 2
So 682771-92-2 is a valid CAS Registry Number.
