1569640-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569640-27-2 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, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1569640-27:
(9*1)+(8*5)+(7*6)+(6*9)+(5*6)+(4*4)+(3*0)+(2*2)+(1*7)=202
202 % 10 = 2
So 1569640-27-2 is a valid CAS Registry Number.
