149221-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149221-76-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,2 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 149221-76:
(8*1)+(7*4)+(6*9)+(5*2)+(4*2)+(3*1)+(2*7)+(1*6)=131
131 % 10 = 1
So 149221-76-1 is a valid CAS Registry Number.
