103987-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103987-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,8 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103987-57:
(8*1)+(7*0)+(6*3)+(5*9)+(4*8)+(3*7)+(2*5)+(1*7)=141
141 % 10 = 1
So 103987-57-1 is a valid CAS Registry Number.
