137649-83-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137649-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,4 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137649-83:
(8*1)+(7*3)+(6*7)+(5*6)+(4*4)+(3*9)+(2*8)+(1*3)=163
163 % 10 = 3
So 137649-83-3 is a valid CAS Registry Number.
