Check Digit Verification of cas no
The CAS Registry Mumber 131841-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,4 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131841-99:
(8*1)+(7*3)+(6*1)+(5*8)+(4*4)+(3*1)+(2*9)+(1*9)=121
121 % 10 = 1
So 131841-99-1 is a valid CAS Registry Number.
