181827-98-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181827-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,8,2 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 181827-98:
(8*1)+(7*8)+(6*1)+(5*8)+(4*2)+(3*7)+(2*9)+(1*8)=165
165 % 10 = 5
So 181827-98-5 is a valid CAS Registry Number.
