1020656-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1020656-76-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,6,5 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1020656-76:
(9*1)+(8*0)+(7*2)+(6*0)+(5*6)+(4*5)+(3*6)+(2*7)+(1*6)=111
111 % 10 = 1
So 1020656-76-1 is a valid CAS Registry Number.
