Check Digit Verification of cas no
The CAS Registry Mumber 104788-47-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,8 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 104788-47:
(8*1)+(7*0)+(6*4)+(5*7)+(4*8)+(3*8)+(2*4)+(1*7)=138
138 % 10 = 8
So 104788-47-8 is a valid CAS Registry Number.
