1425937-60-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1425937-60-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,5,9,3 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1425937-60:
(9*1)+(8*4)+(7*2)+(6*5)+(5*9)+(4*3)+(3*7)+(2*6)+(1*0)=175
