142995-30-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142995-30-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,9 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142995-30:
(8*1)+(7*4)+(6*2)+(5*9)+(4*9)+(3*5)+(2*3)+(1*0)=150
150 % 10 = 0
So 142995-30-0 is a valid CAS Registry Number.
