142980-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142980-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,8 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142980-70:
(8*1)+(7*4)+(6*2)+(5*9)+(4*8)+(3*0)+(2*7)+(1*0)=139
139 % 10 = 9
So 142980-70-9 is a valid CAS Registry Number.
