1569695-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569695-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,6,9 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1569695-57:
(9*1)+(8*5)+(7*6)+(6*9)+(5*6)+(4*9)+(3*5)+(2*5)+(1*7)=243
243 % 10 = 3
So 1569695-57-3 is a valid CAS Registry Number.
