1027987-89-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027987-89-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1027987-89:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*8)+(3*7)+(2*8)+(1*9)=188
188 % 10 = 8
So 1027987-89-8 is a valid CAS Registry Number.
