143237-76-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143237-76-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,3 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 143237-76:
(8*1)+(7*4)+(6*3)+(5*2)+(4*3)+(3*7)+(2*7)+(1*6)=117
117 % 10 = 7
So 143237-76-7 is a valid CAS Registry Number.
