142868-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142868-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 142868-22:
(8*1)+(7*4)+(6*2)+(5*8)+(4*6)+(3*8)+(2*2)+(1*2)=142
142 % 10 = 2
So 142868-22-2 is a valid CAS Registry Number.
