142887-94-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142887-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,8,8 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142887-94:
(8*1)+(7*4)+(6*2)+(5*8)+(4*8)+(3*7)+(2*9)+(1*4)=163
163 % 10 = 3
So 142887-94-3 is a valid CAS Registry Number.
