Check Digit Verification of cas no
The CAS Registry Mumber 144654-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,5 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144654-39:
(8*1)+(7*4)+(6*4)+(5*6)+(4*5)+(3*4)+(2*3)+(1*9)=137
137 % 10 = 7
So 144654-39-7 is a valid CAS Registry Number.
