Check Digit Verification of cas no
The CAS Registry Mumber 141807-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,0 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141807-55:
(8*1)+(7*4)+(6*1)+(5*8)+(4*0)+(3*7)+(2*5)+(1*5)=118
118 % 10 = 8
So 141807-55-8 is a valid CAS Registry Number.
