1536-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1536-29-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 6 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1536-29:
(6*1)+(5*5)+(4*3)+(3*6)+(2*2)+(1*9)=74
74 % 10 = 4
So 1536-29-4 is a valid CAS Registry Number.
