1379535-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1379535-89-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,9,5,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1379535-89:
(9*1)+(8*3)+(7*7)+(6*9)+(5*5)+(4*3)+(3*5)+(2*8)+(1*9)=213
213 % 10 = 3
So 1379535-89-3 is a valid CAS Registry Number.
