104947-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104947-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,4 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104947-68:
(8*1)+(7*0)+(6*4)+(5*9)+(4*4)+(3*7)+(2*6)+(1*8)=134
134 % 10 = 4
