142656-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142656-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,5 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142656-06:
(8*1)+(7*4)+(6*2)+(5*6)+(4*5)+(3*6)+(2*0)+(1*6)=122
122 % 10 = 2
So 142656-06-2 is a valid CAS Registry Number.
