Check Digit Verification of cas no
The CAS Registry Mumber 156049-56-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,0,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156049-56:
(8*1)+(7*5)+(6*6)+(5*0)+(4*4)+(3*9)+(2*5)+(1*6)=138
138 % 10 = 8
So 156049-56-8 is a valid CAS Registry Number.
