142993-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142993-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,9 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142993-41:
(8*1)+(7*4)+(6*2)+(5*9)+(4*9)+(3*3)+(2*4)+(1*1)=147
147 % 10 = 7
So 142993-41-7 is a valid CAS Registry Number.
