1027940-64-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027940-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1027940-64:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*4)+(3*0)+(2*6)+(1*4)=142
142 % 10 = 2
So 1027940-64-2 is a valid CAS Registry Number.
