142653-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142653-70-1 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 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142653-70:
(8*1)+(7*4)+(6*2)+(5*6)+(4*5)+(3*3)+(2*7)+(1*0)=121
121 % 10 = 1
So 142653-70-1 is a valid CAS Registry Number.
