1499238-81-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1499238-81-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,9,9,2,3 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1499238-81:
(9*1)+(8*4)+(7*9)+(6*9)+(5*2)+(4*3)+(3*8)+(2*8)+(1*1)=221
221 % 10 = 1
So 1499238-81-1 is a valid CAS Registry Number.
