1034918-27-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1034918-27-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,9,1 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1034918-27:
(9*1)+(8*0)+(7*3)+(6*4)+(5*9)+(4*1)+(3*8)+(2*2)+(1*7)=138
138 % 10 = 8
So 1034918-27-8 is a valid CAS Registry Number.
