149049-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149049-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,0,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149049-67:
(8*1)+(7*4)+(6*9)+(5*0)+(4*4)+(3*9)+(2*6)+(1*7)=152
152 % 10 = 2
So 149049-67-2 is a valid CAS Registry Number.
