Check Digit Verification of cas no
The CAS Registry Mumber 159144-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,1,4 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159144-07:
(8*1)+(7*5)+(6*9)+(5*1)+(4*4)+(3*4)+(2*0)+(1*7)=137
137 % 10 = 7
So 159144-07-7 is a valid CAS Registry Number.
