149191-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149191-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,1,9 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 149191-92:
(8*1)+(7*4)+(6*9)+(5*1)+(4*9)+(3*1)+(2*9)+(1*2)=154
154 % 10 = 4
So 149191-92-4 is a valid CAS Registry Number.
