133677-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133677-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,7 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133677-83:
(8*1)+(7*3)+(6*3)+(5*6)+(4*7)+(3*7)+(2*8)+(1*3)=145
145 % 10 = 5
So 133677-83-5 is a valid CAS Registry Number.
