141885-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141885-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,8,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 141885-70:
(8*1)+(7*4)+(6*1)+(5*8)+(4*8)+(3*5)+(2*7)+(1*0)=143
143 % 10 = 3
So 141885-70-3 is a valid CAS Registry Number.
