141901-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141901-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,0 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 141901-97:
(8*1)+(7*4)+(6*1)+(5*9)+(4*0)+(3*1)+(2*9)+(1*7)=115
115 % 10 = 5
So 141901-97-5 is a valid CAS Registry Number.
