36992-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 36992-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,9,9 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 36992-25:
(7*3)+(6*6)+(5*9)+(4*9)+(3*2)+(2*2)+(1*5)=153
153 % 10 = 3
So 36992-25-3 is a valid CAS Registry Number.
