143885-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143885-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,8 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143885-72:
(8*1)+(7*4)+(6*3)+(5*8)+(4*8)+(3*5)+(2*7)+(1*2)=157
157 % 10 = 7
So 143885-72-7 is a valid CAS Registry Number.
