138676-96-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138676-96-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,7 and 6 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138676-96:
(8*1)+(7*3)+(6*8)+(5*6)+(4*7)+(3*6)+(2*9)+(1*6)=177
177 % 10 = 7
So 138676-96-7 is a valid CAS Registry Number.
