123883-68-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123883-68-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,8,8 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 123883-68:
(8*1)+(7*2)+(6*3)+(5*8)+(4*8)+(3*3)+(2*6)+(1*8)=141
141 % 10 = 1
So 123883-68-1 is a valid CAS Registry Number.
