143877-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143877-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143877-64:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*7)+(2*6)+(1*4)=159
159 % 10 = 9
So 143877-64-9 is a valid CAS Registry Number.
