1339939-38-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1339939-38-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,9,9,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1339939-38:
(9*1)+(8*3)+(7*3)+(6*9)+(5*9)+(4*3)+(3*9)+(2*3)+(1*8)=206
206 % 10 = 6
So 1339939-38-6 is a valid CAS Registry Number.
