136850-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136850-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,5 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 136850-90:
(8*1)+(7*3)+(6*6)+(5*8)+(4*5)+(3*0)+(2*9)+(1*0)=143
143 % 10 = 3
So 136850-90-3 is a valid CAS Registry Number.
