17882-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17882-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,8 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17882-20:
(7*1)+(6*7)+(5*8)+(4*8)+(3*2)+(2*2)+(1*0)=131
131 % 10 = 1
So 17882-20-1 is a valid CAS Registry Number.
