129368-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129368-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,6 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129368-39:
(8*1)+(7*2)+(6*9)+(5*3)+(4*6)+(3*8)+(2*3)+(1*9)=154
154 % 10 = 4
