149142-33-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149142-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,1,4 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149142-33:
(8*1)+(7*4)+(6*9)+(5*1)+(4*4)+(3*2)+(2*3)+(1*3)=126
126 % 10 = 6
So 149142-33-6 is a valid CAS Registry Number.
