126685-82-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126685-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,6,8 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 126685-82:
(8*1)+(7*2)+(6*6)+(5*6)+(4*8)+(3*5)+(2*8)+(1*2)=153
153 % 10 = 3
So 126685-82-3 is a valid CAS Registry Number.
