Check Digit Verification of cas no
The CAS Registry Mumber 136505-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,0 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 136505-28:
(8*1)+(7*3)+(6*6)+(5*5)+(4*0)+(3*5)+(2*2)+(1*8)=117
117 % 10 = 7
So 136505-28-7 is a valid CAS Registry Number.
