380634-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 380634-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,0,6,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 380634-75:
(8*3)+(7*8)+(6*0)+(5*6)+(4*3)+(3*4)+(2*7)+(1*5)=153
153 % 10 = 3
So 380634-75-3 is a valid CAS Registry Number.
