142729-70-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142729-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,7,2 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142729-70:
(8*1)+(7*4)+(6*2)+(5*7)+(4*2)+(3*9)+(2*7)+(1*0)=132
132 % 10 = 2
So 142729-70-2 is a valid CAS Registry Number.
