1569640-76-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569640-76-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,6,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1569640-76:
(9*1)+(8*5)+(7*6)+(6*9)+(5*6)+(4*4)+(3*0)+(2*7)+(1*6)=211
211 % 10 = 1
So 1569640-76-1 is a valid CAS Registry Number.
