1569905-81-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569905-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,9,0 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1569905-81:
(9*1)+(8*5)+(7*6)+(6*9)+(5*9)+(4*0)+(3*5)+(2*8)+(1*1)=222
222 % 10 = 2
So 1569905-81-2 is a valid CAS Registry Number.
