Check Digit Verification of cas no
The CAS Registry Mumber 157024-69-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,0,2 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 157024-69:
(8*1)+(7*5)+(6*7)+(5*0)+(4*2)+(3*4)+(2*6)+(1*9)=126
126 % 10 = 6
So 157024-69-6 is a valid CAS Registry Number.
