123871-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123871-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,7 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123871-19:
(8*1)+(7*2)+(6*3)+(5*8)+(4*7)+(3*1)+(2*1)+(1*9)=122
122 % 10 = 2
So 123871-19-2 is a valid CAS Registry Number.
